The way of how to test a circuit breaker must also consider the short time that the circuit breaker is out of service minimizing the setup work connections and test complexity.

Dry type hv test transformer. Quick and easy to perform on site. Hv circuit breaker testing video circuit breakers allow the flow of energy to be controlled by safely switching currents on and off at all voltage levels of the energy grid. Why test circuit breaker.

The smc pme 500 tr is a circuit breaker analyzer that includes all the mentioned functions which can be required for the condition assessment of medium and high voltage circuit breakers. Dc hipot test set. Circuit breaker is one of the most important component in every electric power system. How to test a circuit breaker of this type depends on its maximum rated current the trip protection settings and the inverse curve types which will define the overload and short circuit trip pickup levels and time delays.

The circuit breaker has to operate within extremely tight tolerances when a disturbance is detected in the network to protect sensitive and costly components such as transformers. The interrupter and the mechanical drive are the main components that are subject to wear and aging. Oil type hv test transformer. Circuits can be tested on or off load.
