What is ZCT? it operating principle and how is work with
RCCB (residual current circuit breaker)?
Answer Posted / bhoot
ZCT is a neutral CT which is based on zero sequence current
detection. What happens during leakage, the current in the
phases are not the same & hence the in is not equal to
zero. This difference of current flows into the neutral CT
whicgh trips the RCC
