Electric voltage transformer/voltage Sensor/LPVT (Cable Connector type)
1 Apply to
≤24kV busbar connecting system with screened separable connector
Application
♦ Voltage sensor apply to voltage measurement of connecting busbar with screened cable connector in medium voltage gas insulation switchgear of smart grid;
♦ Voltage sensor should be installed on the back of the screened cable connector to replace the position of original rear connector.
