Product Overview
This product is suitable for power systems with a rated voltage of 10kV and a rated frequency of 50Hz. It is an indoor voltage sensor with an epoxy resin insulated pillar structure. It can be used with digital instruments, microcomputer measurement and protection devices to achieve multiple functions such as line voltage measurement and zero-sequence voltage protection. Since the output of the voltage sensor is a small signal, it can be directly connected to the secondary equipment without secondary conversion. It complies with the technical specifications for the integration of primary and secondary power distribution equipment of the State Grid.
