General: The ADR141A is member of Ashida Numerical Relay family (Aditya Series) design to meet demand of low and medium switchgear control. The ADR141A is a 3 OC and 1 EF relay with Instantaneous high set and programmable output to simplify feeder protection wiring. The ADR141A continuously monitors all 3 phase and earth current, through CT connections. The high-speed micro-controller samples this current through a 12-bit A/D converter. The micro-controller performs powerful Digital Algorithms to find out Amplitude of current signal, and then this value is use for protection and metering function. All measurement is tuned to fundamental frequency. Each input current is also displayed on 16 x 2 LCD display for metering. The Relay is having main three functions 1) Protection 2) Self-Supervision 3) Measurement The Relay can be supplied with different model. It can be either Definite Time or IDMT.

Over current / EF protection: The ADR141A has 4 sensing element 3 OC and 1 EF. The tripping current can be set from 50% to 200% for phase and 5% to 80% for Earth fault in steps of 1% by Keys switch provided on front panel. The unit has got selection of IDMT characteristic of international IEC standard Very inverse / Extremely Inverse / Long Inverse and Standard inverse (both 3.0 sec and 1.3sec at 10 times). The unit also has Time Multiplier Setting (TMS) from x0.01 to x1.0 for IDMT delay multiplication. The instantaneous tripping function is having range of 100% - 3000% for phase and 100% - 1200% for EF and can be set in steps of 100%. The high speed CPU continuously monitor the all four current inputs and compare with IDMT as well as instantaneous setting. If any one current is above instantaneous setting the relay provide immediate trip command bypassing IDMT delay. If is input current is less than instantaneous setting but more than IDMT setting, CPU calculate IDMT delay as per selected IDMT characteristic multiply it with TMS setting and provide trip command if fault is persist even after this time delay. All the settings are password protected to prevent unauthorised change. The relay is available in verity of model for different application Ref. Ordering information

1.2.

Extra Alarm Contact: Any Protection panel required extra contacts for provide visual ALARM and ANNUNCIATION indication for operator. Also some status contacts for SCADA or remote indications. Usually separate electromechanical relay used for contact multiplication of protection relay contacts. This added extra wiring and extra hardware. The ADR141A provide separate programmable ALARM contact for such application. Maximum 4 nos. of extra contacts can be provided. These contacts can be programmed as follows

Supervision Function: Self-supervision: The continuously keeping track on its internal hardware and the movement it detect any failure of any component, it give message on LCD display, This feature is very useful to give pre information to avoid any mall - operation. In such situation it use some default setting and remain in protection mode.

3.

Measurement Function: In normal condition this display shows all settings. Via keyboard the display can be program to show the actual current flowing through the relay. If current excesses set value the relay gives trip command. The type of fault is displayed on LCD display. During the fault condition the relay measure the fault current and store in non-volatile memory. The fault current can be read via keyboard on LCD display Last 5 fault values along with tripping counter can be view via keyboard. All settings are save in Electrically erasable read only memory and remain. Ordering Information: The relay is available with nos. of different option. The option is specified by model no. It is user responsibility to specify correct model no. while ordering.
