This portable switch tester is not a general-purpose multimeter: it is purpose-built for the teams that verify the mechanical performance of high-voltage switching devices. It is designed for:
Measure stroke, velocity and bounce time after a mechanism overhaul, confirming that every breaker is rebuilt to specification before it returns to service.
Verify opening and closing times, phase synchronization and contact travel of new breakers before energization during substation commissioning.
Mechanical characteristics verification for new models and routine factory acceptance testing, with full operation waveforms for documentation.
Condition assessment and predictive maintenance of in-service breakers during scheduled outages, catching mechanical drift before failure.
A portable, fast tester that travels easily between client sites for outsourced breaker testing and reporting.
Testing of contactors, relays, air circuit breakers and medium-voltage switchgear inside plants and traction power systems.
It tests all types of vacuum circuit breakers, SF6 circuit breakers, oil-filled high-voltage circuit breakers, load switches, GIS earthing disconnect switches, contactors, relays and air circuit breakers.
Circuit breaker operation time, phase synchronization, bounce time (number of bounces), stroke, velocity, operating voltage, operating current, actuation voltage and full mechanical operation characteristics waveforms.
Current characteristics span 0.1A to 20A at ±2%, while time measurement covers 0.01ms to 18000ms with 0.01ms resolution and ±0.1% accuracy.
Yes. The tester provides 15KV on-site induced voltage immunity, so it remains reliable in live-adjacent substation and GIS testing environments.
It is supplied as standard with 12-channel metal contact time measurement channels and runs on a DC power supply from 35 to 265V with a high instantaneous current of 20A.
