Substation & HV Testing
Test equipment for substations and high-voltage plant: circuit breaker analysers, relay and primary injection test systems, transformer diagnostics, partial discharge monitoring, cable fault location and motor testing. Specialist instruments for utilities, commissioning contractors and industrial test departments rather than general electrical work.
Browse by type
- Cable Fault LocationThumpers, VLF and damped AC test sets, pinpointers and locators for finding and proving faults on LV, MV and HV cable. Pre-location gives a distance along the run; pinpointing puts a mark on the ground, and the two together decide how much of the route has to be dug up.View
- Circuit Breaker TestingTiming and travel analysers and primary injection systems. Timing says whether a breaker will clear a fault in the time the protection assumes; primary injection proves the whole chain from the current transformer through the relay to the breaker itself.View
- Relay Protection TestingSingle-phase and multi-phase secondary injection test sets, phase angle meters and timing references, including IEC 61850 support for digital substations where the protection signals are network messages rather than currents on a wire.View
- Transformer TestingTurns ratio, winding resistance, frequency response, insulation diagnostics and oil testing. Between them these find shorted turns, loose connections, displaced windings, wet insulation and degraded oil - the faults that take a transformer out long before anything looks wrong.View
- Partial Discharge TestingPartial discharge is insulation failing slowly, and it is measurable years before the failure. Monitors, measurement systems and HV test control for cable, switchgear, GIS and rotating machines.View
- Motor & Generator TestingStatic and dynamic testing for motors and generators. Static testing characterises a machine while it is stopped; dynamic analysis assesses it in service under real load, where faults that only appear under running conditions show themselves.View

Send us a model number. We’ll send back a price.
If it is on the shelf you hear back immediately. If we need to source it, two to four working hours — not the two days everyone else quotes.
