Description
Circuit Breaker Tester Repair
A circuit breaker tester (timing and travel analyzer) measures the operating times, contact timing, and travel/motion of medium- and high-voltage circuit breakers to verify they open and close correctly during commissioning and maintenance. June Company repairs and calibrates circuit breaker test sets across the major brands — Megger, Doble, Vanguard, and others — restoring timing and travel accuracy and getting your set back in service.
Whatever the make and model, a breaker tester’s faults concentrate in the timing-measurement inputs, the travel/transducer channels, any control (close/trip) outputs, and the measurement electronics.
Common circuit breaker tester problems we fix
- Timing-measurement faults — contact-timing channels reading wrong, recalibrated against standards.
- Travel / transducer-channel faults — the motion/travel inputs not reading correctly, repaired.
- Control-output faults — the close/trip initiation outputs not firing, repaired.
- Won’t connect or communicate — interface faults, restored.
- Display, control, or power faults.
FAQs
Which breaker testers 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 timing and travel recalibrated? Yes — timing and travel channels 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.
