1 PURPOSE OF TESTSThe purpose of the tests is to check the full functionality of the protection relay.This procedure does not intend to check that all alarms and trips are correctly sent to the DCS or SCADA level. This part is already developed into dedicated DCS or SCADA Commissioning procedures.2 REFERENCE DOCUMENTSDOCUMENTDOCUMENT REFERENCEVERSION/ DATEREMARKS

7 TEST PROCEDURESThe following procedures are written for demonstrating the main protection functions of the P821 relay using an Omicron test set or similar. The tests do not test the boundaries of all available function characteristics. They do test that the function is operating at a point on one chosen characteristic. This document is to be referred to when performing commissioning tests in association with the commissioning section of the service manual.
NOTE :
All the Test are performed in the Test Switch.
Omicron CMC156 Test Equipment or Any Equivalent To Be Used7.1 87RB High Impedance Differential Relay (87 Protection)- Inject Secondary Voltage across the metrosell (Phase R), and increase voltage until the relay operates.
- Record the operating Voltage and current at both the relay terminal and metrosell.-Repeat same procedure above for phase Y and B.7.2 Testing of Binary Inputs :
This test checks that all the opto-isolated inputs on the relay are functioning correctly. (3 opto-isolated inputs for the P122).
The opto-isolated inputs should be energized one at a time. Ensuring correct polarity, connect the auxiliary voltage to the appropriate terminals for the input being tested.
The line "INPUTS" in the "OP. PARAMETERS" menu gives the state of each input, a '1' indicating an energized input and a '0' indicating a de-energized input. When each input is energized one of the digits on the bottom line of the display will change to indicate the new state of the inputs.
7.3 Testing of Binary Outputs :
This test checks that all the output relays are functioning correctly. (6 output relays for the P122).The output relays should be energised one at a time. Connect a continuity tester across the terminals corresponding to output relay 1 .
In the following window in the "Relay Satus" sub-menu of the "OP PARAMETERS" menu:
Relay 8 7 6 5 4 3 2 1
Status 0 0 0 0 0 0 0 1
Repeat the test for each relay.Operation will be confirmed by the continuity tester operating for a normally open contact and ceasing to operate for a normally closed contact.
NOTE: It should be ensured that thermal ratings of anything connected to the output relays during the test procedure is not exceeded by the associated output relay being operated for too long. It is therefore advised that the time between application and removal of relay testing kept to the minimum.If the Outputs are assigned for function this will be tested along with Functional test of relays.
