Description
Protective Relay Test Set Repair
A protective relay test set generates precise voltages, currents, and phase angles to test and commission protective relays and schemes in substations, verifying that relays trip correctly and on time. June Company repairs and calibrates protective relay test sets across the major brands — Megger, Omicron, Doble, Manta, ISA, and others — restoring output and timing accuracy and getting your set back in service.
Whatever the make and model, a relay test set’s faults split between the amplifier/output side and the timing/control side, which is where our repair and calibration focus.
Common relay test set problems we fix
- Output-amplifier failure — a voltage or current channel weak or dead, repaired so every channel meets rated output.
- Timing-measurement drift — trip-time/timing readings out of spec, recalibrated against standards.
- Phase-angle accuracy off — the phase reference, corrected.
- Control / communication faults — won’t connect to or drive from the controller, repaired.
- Display, control, or power faults.
FAQs
Which relay test sets do you repair? Most major brands and models. Tell us the make and model and the symptom, and we’ll confirm the repair and turnaround.
Are outputs and timing recalibrated? Yes — channels, timing, and phase are checked against our standards, with a NIST-traceable certificate.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
