The MK2200 combined overcurrent and earth-fault relay is a digital microprocessor based relay. This relay employs extensive advance numerical techniques implemented in real-time, for the computation of measured input quantity. Other advance features include programmable control output, metering and fault data recording.
APPLICATION
The MK2200 combined overcurrent and earth-fault relay is used where time graded overcurrent and earth fault protection is required.
FEATURES
Multifunction numerical relay
Display of relay settings
Three-phase, low-set and high-set phase overcurrent
9 non- volatile records of previous tripping currents
Low-set and high-set earth fault
Recording of relay start time
Two sets of low-set and high-set setting for earth fault
