DMS 7000 series relays are designed to provide differential protection to two winding transformers, rotating machines (motors or generators) as well as generator-transformer or motor transformer units connected to 50/60 Hz three phase electrical networks.

The DMS 7000 series is made up of two families:

• DMS7001: designed for the protection of synchronous or asynchronous generators or motors
• DMS7002: designed for the protection of two winding transformers and generator-transformer or motor-transformer units.
