Overvoltage Protector for Current-Transformer Protection
CCTP-03
When a power system is in operation, it is imperative that the secondary of the current transformer(s) should not have an open circuit. When an open circuit occurs, an extremely high transient voltage will be induced, which can in turn damage the current transformers and the instruments at the secondary, or even posing a threat to personal safety. This CT secondary overvoltage protector offers protection from such accidental damage caused by secondary transient voltage.
