Medium and High Voltage Breaker Testing (Timing Test Sets)

Electro Rent provides a range of circuit breaker test equipment for applications involving medium (>1000V) and high (>72.5kV) voltages. Measurements include first trip point, timing and travel, moisture content and timing analysis. Although primarily used for testing circuit breakers, the equipment can also be applied to other types of switchgear.

Medium and high voltage test equipment is available from Camlin, DILO, Doble, RH Systems, Vanguard and other manufacturers.

With Electro Rent’s flexible acquisition options you can rent, lease or purchase medium and high voltage breaker testers to meet your short and long-term needs.
