Over-excitation Voltage (59F)
Follow these steps to test that the Over-excitation voltage function is working
properly.
1. Connect a suitable load to the excitation output terminals of the
CGCM-DLR unit.
2. Decrease the field over-excitation voltage setpoint to a level that causes an
alarm.
3. Enable excitation in FCR mode with an FCR setpoint that produces a
field voltage higher than the over-excitation voltage setpoint.
4. Verify that a field over-excitation voltage alarm is annunciated following
the expected delay.
5. Reset the field over-excitation voltage setpoint to the desired level.
Generator Overvoltage (59)
Follow these steps to test that the Generator overvoltage function is working
properly.
1. Set the generator overvoltage setpoint to a level that causes an alarm.
2. Apply simulated generator voltage signals by using the test voltage source.
3. To exceed the generator overvoltage setpoint, adjust the simulated
generator voltage.
4. Verify that a generator overvoltage alarm is annunciated following the
expected delay.
5. Reset the generator overvoltage setpoint to the desired level.
