Corona Discharge from 230kV Disconnect Switch
Corona Discharge from 230kV Disconnect Switch
(OP)
A new 230kV vertical mounted disconnect switch was recently commissioned in a substation and we noticed that significant audible buzzing was coming from the terminals (more than you would normally expect). I am trying to determine the source of the corona discharge and how to mitigate to a more reasonable level. We are using single 1590 AAC single conductor for each of the terminations.
Any thoughts as to the potential sources and/or mitigation strategies?
Thanks

You could buy/rent an ultrasonic camera to pinpoint the area involved.
