MDR-2 Multi differential relay

The MDR-2 is a state-of-the-art combined differential
protection and short-circuit protection relay for generator
protection against internal short circuits (leaking
currents).
Even in cases of fail tripping, the MDR-2 offers
an adjustable tripping characteristic function that
compensates for unbalanced current measurements,
avoiding fail trippings altogether.
The MDR-2 gives you direct access to all settings and a
chronological log of up to 150 historical events/alarms.
The unit’s integrated LCD screen displays all measured
and calculated values, eliminating the need for additional
meters or wiring, and facilitates fault-finding in connection
with commissioning identifying fault locations.
Available options include a block (generator + step-up
transformer) protection option and a short-circuit and
over-current protection option.
