Medium and High Voltage Breaker Testing (Timing Test Sets)


Get Reliable Breaker Readings


Having operating circuit breakers and protection relays is critical during faults to ensure a safe environment for everyone. To make sure this equipment works when needed, it is important to test them often. Precise measurements of circuit breakers require reliable circuit breaker test equipment.


At Electro Rent, our inventory includes a range of high and medium voltage breaker testing equipment. Available circuit breaker test equipment sets are ideal for applications involving >1000V and >72.5kV voltages. All measurements include the first trip point, timing and travel, moisture content, and timing analysis. While these testing sets are primarily used for circuit breakers, the equipment can be applied to other types of switchgear as well.


Whether you need circuit breaker timing test sets or medium voltage breaker testing equipment, discover leading manufacturers, including Camlin, DILO, Doble, RH Systems, Vanguard here.
