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.This procedure does not intend to check all tripping matrix and PSL logic tests, this, when applicable, is described into a separate document, dedicated to the specific substation and feeder type.

7 TEST PROCEDURESThe following procedures are written for demonstrating the main protection functions of the P922 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.

7.1 Testing Over/Under Frequency function

Note : stage (f1>) or (f1) (overfrequency), then configure it at (81) or (f1) or (tf1) check:

1. If time delay (tf1>) is short, gradually increase the frequency from the nominal frequency fn to the value of the stage (f1>): tripping should occur for a frequency in the range [(f1>) 10mHz, (f1>) + 10mHz].

2. If time delay (tf1>) is long, adjust the frequency to [(f1>) 50mHz] and check that tripping does not occur. Increase the frequency to 1.2x(f1>) and check that tripping occurs.

3. Gradually reduce the frequency and measure the value of the drop-off stage (f1>): the function must reset for a frequency less than or equal to [(f1>) 50mHz].

Stage (f1
