DEIF RMQ-111D & RMQ-121D Loss of Excitation Relay/Over-excitation Relay

The RMQ-111D will thus protect the generator against damages caused

by excessive heating due to slip frequency current flow, at the same

time preventing transfer of reactive load from a faulty generator.

The RMQ-121D relay protects generators against overexcitation and will

prevent it from generating too high currents in case of heavy inductive

loads.

The RMQ-121D will thus protect the generator against damages caused

by excessive heating of its windings, at the same time preventing transfer

of reactive load to a faulty generator.
