General:
The ADR145A is member of Ashida Numerical Relay
family (Aditya Series) design to meet demand of low
and medium switchgear control. The ADR145A is a
Directional 3 OC and 1 EF relay with Instantaneous
high set and programmable output to simplify feeder
protection wiring. The ADR145A 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,
direction of power flow 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.
1. Protection Functions:
The ADR145A give maximum benefit/cost ratio. The ADR145A give all the advantage of numerical
relay at affordable cost. Following is summery of different protection functions provided by relay.
ANSI IEC Protection Functions
50 I >> Instantaneous Over current Protection (OC-Inst.)
50N I E >> Instantaneous Earth Fault Protection (EF-Inst.)

1.1. Over current / EF protection:
The ADR145A 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 4 elements are voltage polarised. That means the
IDMT elements can be made directional or non-directional via. Key board setting.
All the settings are password protected to prevent unauthorised change.
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
Function ANN1 ANN2 ANN3 ANN4
Type 1 OC1 OC2 EF OC3
Type 2 OC–IDMT OC-Inst. EF-IDMT EF-Inst.
2. Supervision Function:
2.1. 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.
Note: Due to our policy to upgrade our products constantly, we reserve the right to supply products which may vary
slightly from that indicated above.

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 3 fault values along with tripping counter can be view via keyboard.
All settings are save in Electrically erasable read only memory and remain.
