Power distribution for digitalized industry

Have you claimed your free Siemens ticket for Hannover Messe yet? From April 13 to 17, the leading international trade fair is again addressing exciting trends and topics, and Siemens, as usual, is setting standards with its booth. Under the slogan “On the way to Industrie 4.0 – Driving the Digital Enterprise,” the focus this year is on the increasing digitalization of industry. As part of the digitalization process, industrial power grids will be provided with digital and additional measurement and automation systems as well as options for control and regulation. This development presents industrial enterprises with new challenges as they look to increase the energy efficiency of their plants, ensure security of supply, and secure increasingly complex plants and systems against overloads and short circuits with modern protection systems. Our holistic solutions meet these challenges for sustainable and cost-effective power supply with Totally Integrated Power, which we are presenting at Booth D35 in Hall 9. These solutions include an enhanced version of the communication-­ capable 3VA molded case circuit breaker from the Sentron portfolio, which we are also presenting in our cover story. Furthermore, we show you our systems for power monitoring with powermanager software and measuring devices (see how these prove themselves in industrial practice, starting on page 28). But of course the new E-Installation is not just about solutions for industry. As always, we inform you about our new products for electrical installation in residential and nonresidential buildings and for switching technology for medium-­ voltage systems. And we again present some interesting examples, such as how your colleagues have provided for comprehensive fire protection in a historic inn and in Berlin’s famous KaDeWe, and how a dynamic learning environment was ­ensured in a new school through energy-efficient lighting. Oh, and if you do not yet have your free Siemens ticket for Hannover Messe, on page 35 you will find the QR code to use your smartphone to go directly to our Hannover Messe website.

here is no question about it: molded case circuit breakers are among the most important protective components in large residential and commercial buildings as well as in industrial manufacturing facilities. After all, they protect the electrical equipment and installations in case of faults such as short circuits and overloads. But their benefits now go far beyond that protection, thanks to new technical capabilities. Of particular importance is their ability to detect and transmit energy and power data, which allows them to serve as an important basis for efficient, reliable processes in automated environments. To optimize this efficiency, high transparency of all consumption values and system states

is required. In order to deliver their full value, circuit breakers must be able to accurately detect measured values and provide appropriate interfaces for their transfer – as do the molded case circuit breakers of the 3VA2 series.

Data suppliers to higher-level systems Although communication-capable mol­ ded case circuit breakers can also be used as separate, independent information suppliers, using and processing the data in higher-level building automation systems is much more effective. Due to the ever-increasing demand for energy in manufacturing processes, integrating the energy data from the

power distribution system into the com­pany’s higher-level systems is particularly important. That is why the Totally Integrated Automation (TIA) automation strategy also includes protection devices such as circuit breakers and measuring devices for energy data acquisition from power distribution and equipment. For efficient automation of commercial and large residential buildings, Total Building Solutions (TBS) integrate all building services in one system, and molded case circuit breakers can provide the basic electrical consumption data here as well. Last but not least, these devices are also an integral part of Siemens’ solutions for s ecure electrical power distribution: ­ Totally Integrated Power (TIP) guaran-

Communication-capable 3VA2 molded case circuit breakers

Communication creates transparency In terms of the benefits of molded case circuit breakers, the ability to communicate is the icing on the cake. The new devices in the 3VA2 series thus become an excellent information system: used in higher-level energy management or automation systems, the data collected create transparency and lay the foundation for systematic energy monitoring.

3VA molded case circuit breaker

Technical requirements In order for molded case circuit breakers to be integrated into automation environments, they must be able to communicate using standard protocols. The 3VA2 series meets this requirement with special electronic trip units (ETUs). The ETUs of the 8 series include a measurement function for current, voltage, consumption, and power data. If only current needs to be detected, ETUs of the 5 series are the ideal solution. Switch state levels and maintenance information are collected using the ­ ETUs and forwarded via data concentrators to higher-level systems. The data are transferred using the com­ mon Profibus, Profinet, and Industrial Ethernet (Modbus TCP) bus systems. The molded case circuit breakers are quick and easy to parameterize, commission, and maintain using the Powerconfig software.

Modern protection system for electrical installation in historic inn

Siemens AG/W.Geyer

Safe, comfortable environment The “Beim Füchsle” inn in the Allgäu region of Germany relies on tradition combined with modern technology. A modern electrical installation ensures smooth operation. The powerful fire alarm system and central building control meet the highest standards of safety, protection, and comfort.

T

he 200-year-old farmhouse that today serves as the “Beim Füchsle” inn is located in the small village of Kirch-Siebnach, in the middle of a green Allgäu countryside. Just outside the door is the old Way of St. James. Pilgrims, hikers, cyclists, and day-trippers can find everything they need to take a break here. Almost 10 years ago, Melanie Gebler and Ludwig Seitz took over the then-vacant family property. Since then, the two have been working tirelessly to modernize this rare jewel with great care. In the summer of 2013, the building was extended to include a generous new addition with seating for an additional 90 guests and a restaurant kitchen with modern

8

equipment. As the owners discussed the replacement of the dilapidated barn next to the historic main house, they agreed: “We wanted the highest standards in all areas. And that also means perfect, functional technology, which does not necessarily have to be visible to the guest.” Both in the new building and in the historical part, the project team paid special attention to the electrical installation. The existing cables and socket outlets were still in compliance with standards, but they no longer corresponded to current capabilities relating to safety and comfort. An additional challenge was the limited capacity of the incoming cable from a regional energy supplier to the remote location.

Protection concepts | E-Installation 1/2015

Monitoring and comfort All electrical energy flows are monitored with a Sentron measuring device from the 7KM PAC series. At load peaks, individual loads are automatically reported and switched off in an orderly manner as soon as a defined limit value is reached. This makes it possible to reliably operate the restaurant even at full capacity utilization, and it also helps save power. At the same time, the supply and infeed of unneeded energy – from the photovoltaic system, for example – are monitored. Heating, lighting, and ventilation provide for a pleasant environment in the dining rooms and guest bedrooms. Everything is controlled using the flexible and scalable Gamma instabus KNX bus system. The attractive high-quality single switch with KNX func-

Light and ventilation in the rooms are easily controlled using a modern KNX system with a central touchpanel control station

The overall solution developed by Siemens therefore relies on transparency and controlled processes in power consumption. Powerful protection components for the electrical installation, a measuring device for monitoring the electrical energy flows, a KNX system for the central building control, and an automatic fire alarm system meet the highest standards of safety, protection, and comfort. Appropriately designed miniature circuit breakers (MCBs) secure the many electrical loads through­ out the building complex, including highly energy-­ intensive systems such as refrigerators and water decalcification units, against overloads and short circuits caused by operation as well as short circuits in cables and wires. Residual current circuit breakers (RCCBs) protect people from electric shock. To ensure the complete safety of the electrical installation in the “Beim Füchsle” inn, 15 additional arc fault detection units were installed. These devices also respond to serial arc faults, which cannot be ­detected by MCBs and RCCBs, by switching off the ­affected circuits safely within a fraction of a second. This eliminates possible causes of electrically induced fires. Dining rooms, bedrooms, kitchens, and technology areas are also monitored and protected with 50 automatic fire detectors. In case of fire, the system immediately triggers a warning tone and reports the fire simultaneously to the Sinteso FC2020 fire control panel. People are warned early and can safely leave the premises. An automatic display shows the exact location where the fire has started.

Gebler sees this as very practical, especially at the end of business hours, as it eliminates the need for unnecessary walking.

Electrical professional Michael Hafemeister, who with his Hafemeister Plan GmbH is a longtime specialist partner, had the solution at hand: the Siemens arc fault detection units, which is unique in Europe. It detects dangerous arc faults automatically and reliably, and immediately and safely switches off the affected circuits, thus complementing the usual protective devices and creating an integrated protection system. “With this device, we can now for the first time successfully address

The first arc fault detection devices, which he installed in the distribution board relevant to the atrium area, have already experienced their first “baptism by fire”: The water vacuum cleaner of a workman caused a serial arc outside business hours. The affected circuit was switched off immediately so there was no risk of fire. For this reason, the commercial kitchens on the restaurant floor and other distribution boards in fire-sensitive areas are to be successively retrofitted with arc fault detection units.

charging station or pillar is not a lways needed: the CC100A ­ charging cable is a safe and convenient alternative for charging ­ electric vehicles – at home or on the road. It connects to standard household socket outlets and is compa­ tible with the most common types in Europe, thanks to various plug variants. In this way, the mobile charging unit in charging mode 2, in accordance with IEC 61851, can serve as an emergency charging cable if an accessible charging pillar is not available. The interna­tio­ nally common camping plug (CEE blue 6 h) even allows faster single-­ phase charging with 16 A and a charg­ ing power of 3.7 kW. Because the CC100A charging cable is available with vehicle-side charging couplings of type 1 or type 2, it is suitable for almost all commercially available electric vehicles. The control box can be operated in­ tuitively using self-explanatory symbols. It allows quick adjustment of the charging current to any home installation, and the fixed charge current upper 16

limit is transmitted to the connected vehicle. In addition to excellent user-friend­ liness, the cable ensures maximum safety for people, vehicles, and electrical infrastructure. An electronic RCCB of type A is integrated into the box, which satisfies the conditions for safe charging of electric vehicles in accordance with IEC 61851. Multilevel temperature management prevents thermal overload. The control box indicates via LED if the charging process has been automatically interrupted due to high temperatures. Thanks to its robust design, the charging cable is durable and weather resistant. The enclosure and the charge coupling can be driven over and are resistant to environmental influences such as dirt, moisture, and temperature fluctuations. The control box even features the high degree of protection IP67.

ower failures can lead to very critical situations. If the power fails in a hospital, for example, all patient care is paralyzed, thus threatening the life of the patients. To ensure uninterrupted power supply in infrastructure and in continuous industrial processes, control devices are used that automatically switch to a second power supply in case of malfunctions. The 3KC ATC3100 transfer control device, with its large voltage range of up to 230/400 V AC, is suited for low-voltage power distribution applications in which two independent power supplies are required as a main and reserve system. The device simultaneously monitors two networks; detects power faults such as overvoltage or undervoltage, phase failure, or a fire alarm signal; and can be used for switching from network to network or from network to generator and vice versa. The changeover can be carried out automatically with a set delay time or manually. In conjunction with 3WL/3WT air circuit breakers or 3VA/3VT molded case circuit breakers, the control system meets international standards. Complete schematics are available for the configuration of changeovers with switches from the Sentron portfolio. With its low mounting depth of only 99 mm, the 3KC ATC3100 transfer control device is suitable for front, standard mounting rail, or rear wall mounting and can be wired quickly thanks to removable terminals. The front side of the device is designed in degree of protection IP41 and can also be locked with a transparent protective cover.

3VA molded case circuit breaker

Improved selectivity and optimum motor protection The 3VA molded case circuit breaker offers several innovations. With an optimized characteristic curve (Elisa) with the overcurrent releases, circuit breakers can be selectively staggered as required in combination with downstream fuses. New starter and motor protection variants supplement and complete the 3VA portfolio.

E

lisa describes a special current-­ time characteristic curve that is stored in the molded case circuit breakers of the 3VA2 series with an ETU 340 Elisa up to 630 A. It improves selective staggering of upstream circuit breakers in combination with downstream fuses. Due to the Elisa characteristic curve, the rated current distan­ ces between circuit breaker and fuse can be selected as required. This can result in smaller rated currents for the circuit breaker, allowing smaller, cost-­ saving sizes to be selected. Due to the steeper expression of the Elisa characteristic curve, the switch-off occurs earlier in case of overload with the same protective behavior, compared to an LSI characteristic curve, thus reducing the electrical load of the equipment. In addition, parameters can be set for ETUs with Elisa characteristic curves more easily than with standard LSI characteristic curves: with ETUs with Elisa characteristic curves, only the response current of the overload protection I[A] needs to be set.

200 A protects against short circuits. A separate overload relay is required for protection against overloads. The 3VA2 motor protection variant from 25 A to 500 A features full motor protection as a complete assembly. The ETUs of this series are equipped with characteristic curves optimized for motors. Phase sensitivity and thermal memory protect the motor from overheating. Using an adjustable inertia class, the overload release can be set to suit the restart conditions of the motor to be protected. Optimal motor protection for drives is consistently guaranteed up to 200 kW. The ETU 860M also enables energy data acquisition and the transmission

of power and energy data of large drives up to 200 kW – for load management, for example. Whether starter protection or motor protection is required, one motor contactor is used for operational switching. In either case, the molded case circuit breaker also serves as a disconnector to de-energize the motor for maintenance purposes, for example.

Power monitoring supports Fraunhofer IISB in the SEEDs project for sustainable energy use

In the research project SEEDs at the Fraunhofer Institute for Integrated Systems and Device Technology (IISB), sustainable energy models and systems are developed for small and medium-sized industrial enterprises. The research work is supported by the software powermanager and measuring devices from Siemens.

H

ow can energy be sustainably generated and used efficiently under industrial conditions? What effects on the whole system do factors such as line harmonics and reactive power or secondary forms of energy such as cold, heat and process gases have? The answers to these questions have been pursued by the Bavarian Ministry of Economic Affairs research project SEEDs since early 2013. At Fraunhofer IISB, located in ­Erlangen, Germany, Dr.-Ing. Richard Öchsner spearheads the initiative. As the head of the power engineering area, he coordinates all SEEDs activities of the three participating Fraunhofer institutes.

What was needed was an open system that could be easily retrofitted and flexibly expanded with many different measuring devices. The quality of the data supplied also needs to meet the demands of a long-term research project. The team led by Richard Öchsner chose the software powermanager version 3.0 from Siemens: “Very flexible, very open, and at the same time extremely powerful – in accordance with our requirements.” The software runs at Fraunhofer IISB as an independent system on a W indows PC and is integrated via ­ Modbus TCP in an Ethernet LAN network. It monitors and archives the data of 50 measuring points in different ­devices. The export function in Excel is also valued by the team. The data can be processed and correlated simultaneously with the building control system. Electrical energy data such as voltages, currents, power, energy values, and frequencies are usually measured directly

A total of 15 7KM PAC3100/3200 measuring devices and 8 multi-master-capable 7KM PAC4200 units reliably provide the various energy data up to the system level

via measuring devices from the Sentron port­folio. A total of 15 standard 7KM PAC3100/3200 models and eight multi-­ master compatible 7KM PAC4200 units enable the data capture up to the system level. A Sicam Power Quality Recorder also documents voltage and network quality.

Energy flows are transparent Some two years after the start of the project, more than 90 percent of the energy flows at Fraunhofer IISB can now be precisely tracked using the powermanager software. The entire energy monitoring system is updated every second in real time. By means of this short interval, electrical energy storage devices can be switched on and off according to precise needs. This way, real savings in the form of electrical and thermal energy can be achieved.

The data collected is used for documentation and as a basis for further research. The precise analysis of energy flows reveals optimization potential in everyday operation. This enabled starting points for energy improvements throughout the building and in the existing building of Fraunhofer IISB to be determined. For example, the first optimization opportunities were identified in the operational strategies for the concrete core activation and for coupled heat pumps. The support for error detection using the data obtained makes the energy monitoring system also interesting for other areas of the institute.

All measuring devices, as well as the PC running powermanager, are compactly and clearly incorporated into a single Alpha cabinet from Siemens. This allowed the entire solution to be completely installed and tested at actensys in advance and put into operation quickly and easily on-site. In addition to the components for the power monitoring system, the cabinet contains all the necessary protective devices, such as miniature circuit breakers, residual current circuit breakers, and a surge protector. This comprehensive protection solution is particularly important for the precision tool manufacturer because indi­ vidual machines are running around the clock in unmanned automatic mode in some cases. The solution is rounded out with an LV HRC fuse from Siemens, with which larger currents, such as those that occur in the BD02 busbar trunking systems from the Sivacon 8PS line used at Mader, can be safely conducted and disconnected.

Energy-efficient lighting with KNX and DALI

Dynamic learning environment The four-stream Prüfening Elementary School in Regensburg, Germany, is a modern school in every respect: a communicative place for almost 400 students and their teachers, with optimal learning conditions – along with maximum cost-effectiveness and energy efficiency – created by the city and the office of twoo Architekten of Cologne.

This meant that the current energy efficiency standards were to be exceed­ed by least 30 percent – as with all new buildings in the city. For the electrical engineering, only an automated, centrally managed solution with KNX came into consideration by the IB PEMA planning office from Regensburg and the Weikl electrical installation company from Bodenmais. Together with partners from Siemens, the team planned all the energy-related aspects – from the building structure to heating, ventilation, sun protection, and lighting – with specific building simulations.

DIN EN 61439 standards for switchgear and control system implementation

Siemens AG

New standards for planning and design Since November 1, 2014, the new DIN EN 61439 series of standards for switchgear and control system implementation has come into force, definitively replacing the prede­cessor standard DIN EN 60439-1. What does that mean for manufacturers and users?

T

he new standard harmonizes the specifications and requirements for low-voltage switchgear and controlgear assemblies. The requirements and verifications for switchgear and controlgear assemblies are standardized, and verifications in accordance with other standards are now unnecessary. DIN EN 61439-2 applies to energy switchgear and controlgear assemblies comprising at least one item of low-­ voltage switchgear. The main functions of the standard relate to the three areas of safety, functionality, and availability of power distribution boards in low-­ voltage switchgear.

Design verification redefined

the “original manufacturer” and the “manufacturer of the switchgear and controlgear assembly.” The original manufacturer must ensure that there is a type verification for the switchgear and controlgear assembly or for the original system. The system can consist of a variety of products, each with its own type verification. In this way, the manufacturer of the switchgear and controlgear assembly can vary the configuration of the system. For an original system without changes, the original manufacturer of the switchgear and controlgear assembly needs to provide only the routine verification. In case of any modification of the original that affects the existing design ­verification of the original manufactu­ rer, the manufacturer of the switchgear and controlgear assembly automatically becomes the original manufactu­ rer for these changes. This means that it now needs to provide the design verification and routine verification and document everything completely.

With the newly introduced design verification, the TSK and PTTA verifications from DIN EN 60439-1 have been replaced. According to the new regulation, the original manufacturer is responsible for the design verification. Switchgear and controlgear assemblies that have already been examined according to the old standard and whose Interface features test results meet the requirements newly regulated of DIN EN 61439-2 do not need a new The new DIN EN 61439-2 standard spec­design verification. In terms of product responsibility, ifies what criteria must be defined beDIN EN 61439-2 differentiates between tween the manufacturer and user of the

switchgear and controlgear assembly for interface features. According to these criteria, the manufacturer of the low-voltage switchgear and controlgear assembly then ensures that the characteristic features of the system correspond to the defined criteria and produces, tests, and documents a switchgear and controlgear assembly that conforms to the application and the standards. The switchgear and controlgear assembly is seen as a “black box” with four interface areas for the environment: installation and ambient conditions, operation and maintenance, connection to the electrical grid, and electrical circuits and loads. If everything is to be carried out in a standards-compliant manner from planning to operation, maintenance, and ­repairs, the reliable functioning of low-­ voltage switchgear and controlgear assemblies must be ensured. Siemens supports manufacturers and users of low-­voltage switchgear in the configuration, manufacture, and delivery of complete control cabinets.
