RMQ-111D & RMQ-121D https://deif-staging.jcdhotel.dk/products/rmq-111d-rmq-121d/ Loss of Excitation Relay/Over-excitation Relay en Thu, 18 Jun 2026 05:22:11 GMT Active fe80ec8d-3cf3-4808-90c8-0b746e6526c7 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.
