ZW32 zero-phase integrated electronic voltage sensor voltage transformer for phase and zero-sequence voltage protector
JY.EVT-10/32-L/C zero-phase integrated electronic voltage transformer is a new type for phase and zero-sequence voltage protector. The electronic voltage sensor adopts advanced voltage dividing technology, which can accurately collect zero-sequence voltage. The transformer is used in conjunction with the circuit breaker on the outer column of the outdoor high-voltage vacuum circuit breaker and the switch cabinet, and is widely used in various power distribution systems.
