Vacuum circuit breaker test equipment.

How to test a circuit breaker involves many different test techniques and type of testers. Vidar enables you to check the integrity of the vacuum interrupter quickly and conveniently by means of the known relationship between the flashover voltage and the vacuum interrupter. A suitable test voltage dc is applied to the breaker and the result is known immediately. Recommended test is the equipment power frequency withstand or vacuum integrity test using the voltage specific to the interrupter open gap.

When the breaker operates the moving contact separates from the fixed contact and an arc is struck between the contacts. A means of giving harmless vent to excessive energy in a circuit thereby minimizing the risk of damage to equipment that would otherwise be subjected to non design conditions. Various power system components depend on the proper operation of a circuit breaker including for example expensive power transformers. The working of vacuum circuit breakers is briefly explained below.

Circuit breakers are the metaphorical safety valves of electrical systems. Using a test current less than 100a is acceptable but know that equipment manufacturers usually don t recognize warranty claims based on a 10 ampere dlro test. Circuit breaker test equipment perform testing of circuit breakers and relays current transformers ground fault trip devices or use in other applications that require a high current power source. While the current method produces good results and has shown very high reliability for the interrupter tube there is still infrequent insistence that the vacuum level be quantified beyond a pass fail.
