1.
When the parameter
9020 Phase O/C
for Busbar Energization is set to
ON
and bus-tie CB is closed, Phase
overcurrent for busbar energization protection will start to run. The running time is set by the parameter
9019A Active Time
for Busbar Energization.
2. Compound voltage control can be enabled or disabled by setting the parameter
9021 Compound Voltage
Control to
YES
or
NO
.
3. PT broken wire cannot block phase overcurrent for busbar energization protection.
4.
After the trip signal is released, the dropout of the voltage signal cannot reset the trip signal, only current
dropout can reset the trip signal.
