The DVG-3 voltage transformer is designed for use with watt-hour meters, relays, and in other control applications. The unit consists of 1, 2, or 3 revenue metering accuracy voltage transformers, depending on the application. Primary and secondary connections are made using a wiring harness that connects to the connector provided on the voltage transformer.


The core and coil assemblies are encapsulated in polyurethane inside a UV-resistant Valox case.

Primary and Secondary Connections

Primary and secondary connections are made via a 9-position Molex connector plug system. A wiring harness must be purchased with each voltage transformer to facilitate connections to the line and the connected device.
