Z2, BREAKER OPENED, BREAKER CLOSED, and FAULT CLEARED. Next, with the
breaker closed (CC1 without power) and with channel reception (CC6 with power applied),
momentarily apply the currents and voltages indicated by the AG80 fault checking that the
relay trips and recloses and that the last events generated were TRIP IN ACCELERATED
Z2, BREAKER OPENED, BREAKER CLOSED, and FAULT CLEARED (the event(s)
MEAS_UNIT ACT and/or OPEN BRK CURR. may appear at the same time as one of the
previous events or be inserted among them).
If you have a stop watch, you can observe that an accelerated Z2 trip must be
faster than a Z2 trip.
6.2.11. LPU FUNCTION
Set the following protection setting:
202 - LPU IN SERVICE
YES
Apply the voltages and currents corresponding to a balanced system, but instead of
applying the rated voltage, apply more than 3 times the rated voltage of the relay. Ensure
that tripping by LPU is permitted and that the MLP sees the breaker open (for this use the
latching relay which simulates the breaker in position 0).
To check the LPU function there are 2 tests:
In the first test the CC-3 input contact (LPU input) is activated and check that the
LPU trips the relay. This is checked by observing the trip contacts and the trip message on
the monitor.
In the second test, instead of activating the LPU input, perform the close breaker
operation and check for the same conditions as in the first test.
