FLASHING ON A METERING CB
FLASHING ON A METERING CB
(OP)
We have undertaken studies on the cause of flashing on a yellow phase spout. The latest having destroyed the 11kV indoor CB. The CB was installed for a client whose load is mostly compressors, airconditioners and freezers. What could be the likely causes and what remedies do you suggest. This is the third time the spout flashed and a solution must be found.
Thanks guys

Something that imposes overvoltages on the yellow phase.
A faulty lightning arrestor somewhere upstream comes to mind.
