Product Specification

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.

Features

• It is mainly used to test the zero sequence and phase sequence voltage, with high precision and stable and reliable operation
• The transformer adopts the Capacitive voltage divider principle and liquid independent packaging technology
• The transformer consists of three-phase independent sensors with high-voltage wires, which can be directly connected to the high-voltage conductors of the main switch
