Regarding the disactivation of the CT overvoltage protector
Thread Content
What is the impact on operation when the current transformer overvoltage protector is disabled (by disconnecting the power cable), and what is the impact on the operation of the protection devices? Accident details: The 4# main transformer in the backoffice reported an abnormal longitudinal differential current, indicating a fault in the CT overvoltage protector; after disabling the protector, operations in the backoffice resumed normally. I would like to ask the experts: are there any issues if we continue to operate it?
It’s not a big problem if it’s due to a protector failure causing shutdown
