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
