Acceptance and Maintenance Tests
In the field using a portable primary injection test kit, maintenance and Acceptance tests are carried out specially intended to be smaller than factory test equipment.
For proper operation Circuit breakers with electromechanical or thermal-magnetic trip devices may only be tested using the primary current injection technique. The secondary current injection may test circuit breakers equipped with solid-state trip mechanisms, saving time and money.
Primary Current Testing
A primary injection testis performed by passing a predetermined series of overload and fault magnitude currents. It is effected using a circuit breaker and recording how long it takes the trip unit to trigger. Electricity is continuously injected into all three poles of a circuit breaker when these tests are conducted in a repair facility or factory.
Integration
In the test set fault current or simulated overload is supplied by an integrated high-current transformer. Test sets with current ratings ranging from 500 to 100,000 amperes are constructed. Acceptance and maintenance tests are carried out in the field using a portable primary injection test set specially intended to be smaller than factory test equipment. These smaller test sets are often incapable of concurrently injecting electricity into all three phases of a circuit breaker.
