MCDGV4 - GENERATOR DIFFERENTIAL PROTECTION

The “all-inclusive” generator differential protection relay MCDGV4 is a high precision protection for medium and high power generators. The step-up transformer can be integrated into the protection zone (unit protection/ block protection). In addition to the phase and earth differential protection, the device provides a variety of generator-specific protection functions
