HighPROTEC MCDGV4

Generator Protection

The 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. The “all-inclusive” package comprises also phase, earth current, voltage, frequency and power protection. In addition to that the device offers an undervoltage directional reactive power protection with reconnection function and an adjustable Fault Ride Through (FRT) with AR detection. The intuitive operating concept with plausibility checks and extensive commissioning functions such as the built-in fault simulator allows a safe and time-optimized maintenance and commissioning. The parameter setting and evaluation software Smart view SE can be used consistently across the entire family of devices. The MCDGV4 is available in 384 variants, that cover all combinations of properties that you might need or not need for your application. Each variant is uniquely specified by a typecode of form MCDGV4-2xxxxx (i.e. 5 digits/letters following the '-2'). Check the Order Form (depicted below, or in the brochure DOK-FLY-MCDGV4-2E or in the user manual MCDGV4-3.6-EN-MAN) for a complete overview.
