RMQ-111D, Loss of excitation relay, -Q>

This Uni-line relay protects generators running in parallel with other generators from running as an induction generator due to under-excitation – particularly in cases where applying an under-voltage relay for protection is insufficient.

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.
