Megger PS-9160 Circuit Breaker Test Set Repair
The Megger PS-9160 is a circuit-breaker test system — it tests circuit-breaker timing, motion/travel, contact resistance, and coil performance to verify that breakers open and close correctly during maintenance. As a multi-measurement breaker analyzer, its faults span the timing/measurement channels, the high-current contact-resistance source, and the control electronics.
June Company repairs and calibrates the Megger PS-9160 for utility relay technicians and substation maintenance crews.
Common Megger PS-9160 problems we fix
- Timing-measurement drift — breaker open/close timing readings out of spec, recalibrated against standards.
- Travel / motion-transducer channel faults — the motion-analysis inputs not reading correctly, repaired.
- Contact-resistance source faults — the high-current source for resistance measurement, repaired.
- Coil / control-measurement faults — the coil-current channels, restored.
- Won’t connect to the control PC — interface faults.
FAQs
My PS-9160 timing or travel readings are off — fixable? Yes. Timing and measurement-channel faults are repairable and recalibrated, then verified so breaker analysis is accurate, with a NIST-traceable certificate.
Are all channels verified? Yes — timing, travel, resistance, and coil channels are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
