Crest Test Systems Pvt. Ltd.
AC and DC power supplies are used for providing the power required for energising the trip and close coils of the breaker and for running the spring charging motor. The appropriate AC or DC configuration of the power supplies can be selected, depending on the DUT specifications of the manufacturer. Dual-mode AC/DC power supplies capable of providing AC and DC outputs from the same power supply are also available, if required by the user.

Measuring contact timings is useful for finding the contact bounces and non-simultaneity of contacts. This helps in finding the possible electrical or mechanical defects in the circuit breaker contacts. Timing analysis also make it possible to detect incorrect mechanical adjustments and wear phenomena of the circuit breaker by measuring the differences between the fastest and slowest phases.
