General:The ADR211E is member of Ashida Numerical Relay family (Aditya Series) design to meet demandof low and medium switchgear control. The ADR211E is single pole EF relay with instantaneous highset and programmable output to simplify feeder protection wiring. The ADR211E continuouslymonitors earth current, through CT connections. The high-speed micro-controller samples thiscurrent through a 12-bit A/D converter. The micro-controller performs powerful Digital Algorithmsto find out Amplitude of current signal, and then this value is use for protection and meteringfunction. All measurement is tuned to fundamental frequency. Each input current is also displayedon 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 ADR211E give maximum benefit/cost ratio. The ADR211E give all the advantage of numericalrelay at affordable cost. Following is summery of different protection functions provided by relay.

1.1. Protection Function:

The ADR211E has single element (EF). The tripping current can be set in dual stage from3% to 80% in steps of 1% by Keys switch provided on front panel. The unit has selectionof IDMT characteristic of International IEC standard, Very inverse / Extremely Inverse /Long Inverse and Standard Inverse (3.0 sec, 1.3sec, 1.5 Sec, 0.8 sec & 13.3 sec at 10times). The unit also has Time Multiplier Setting (TMS) from x0.01 to x1.0 for IDMT delaymultiplication. The instantaneous tripping function is having range of 100% - 1200% insteps of 100%. The high speed CPU continuously monitors the current input andcompares with IDMT as well as instantaneous setting. If current is above instantaneoussetting the relay provides immediate trip command bypassing IDMT delay. If is inputcurrent is less than instantaneous setting but more than IDMT setting, CPU calculateIDMT delay as per selected IDMT characteristic multiply it with TMS setting and providetrip 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

2.0 Supervision Function: -2.1 Self-supervision: -

The continuously keeping track on its internal hardware and the movement it detect any failureof any component, it give message on LCD display, This feature is very useful to give preinformation to avoid any mall - operation. In such situation it uses some default setting andremains in protection mode.

3.0 Measurement Function:In normal condition this display shows all settings. Via keyboard the display can be program toshow the actual current flowing through the relay. If current excesses set value the relay givestrip command. The type of fault is displayed on LCD display.During the fault condition the relay measure the fault current and store in non-volatilememory. The fault current can be read via keyboard on LCD display Last 5 fault valuesalong with tripping counter can be view via key-board. All settings are save in Electricallyerasable read only memory and remain.
