Our solution
Benefits MC 774
The management of Elektro Gorenjska wanted to have better insight into power quality related power grid parameters within transformer stations. For this reason we proposed equipping a majority of their MV/LV transformer stations with network analyzers MC 760, network recorders MC 750 and some power quality analyzers MC 774. Characteristics of our measuring devices are described below.

At the beginning of 2014 our system for electrical quantities recording and power quality monitoring consisted of approximately 260 measuring centres: MC 750, MC 760, MC 774 and software MiSmart. The key advantages after introducing the system are:
Meter points 5
MC 774 Power Quality Analyser
MC 760 Network Analyser
MC 750 Network Recorder
ź Remote and centralized measurement monitoring of different electrical quantities (energy, active power, reactive power, currents, voltages,
phase angles, maximal period values, minimal period values) ź Remote and centralized alarm monitoring in real time – alarms are sent into the system upon appearance
We also had to properly address the problem of data collection from transformer stations. For this purpose we introduced the MiSmart server for remote monitoring and collecting operational measurements from transformer stations. These recorder measurements were setup to include energy counters, powers, power factors, voltages, currents etc. Recorder evaluation periods were set at 1, 5 or 10 minutes meaning that all data was sent to the server immediately after evaluation and successful storage into the device recorder. Along with recorded measurements our system also provided real time alarm information to the electro-distribution company. This was setup by using alarms about voltage absence, overvoltage undervoltage, overcurrent andfrequency deviations.. Alarms also enable detection of overheating of interior of transformer stations or physical intrusion.
ź Power quality parameter monitoring according to EN50160 on 19 locations ź Real time information on the operation of installed equipment ź Excel and PQDIF data export capability for regulator reporting ź Better and faster maintenance planning according to historic data offered by the system ź Quicker response to failures aswell as failure analysis ź Better supervision over energy losses within the power grid by comparing consumption data with the one of the billing system
. ź SCADA system integration over the IEC 60870-5-104 protocol
