Test Static Trip I, II, & III Trip Units with the Siemens PTS-4

Siemens_PTS-4.jpgTest Static Trip I, II, & III trip units used on the LA and RL line of low voltage power circuit  breakers with the Siemens PTS-4 (PTS4) Secondary Injection Test Set.

The test set provides a means of testing the magnetic tripping  actuator as well as the trip unit. The portable test set, using power from an ordinary 120 volt convenience outlet, can provide circuit breaker testing equivalent to much more expensive and cumbersome primary current testing. 

With the  Siemens PTS-4, Static Trip III trip devices can be tested by themselves, or on a circuit breaker outside the cubicle, or inside the cubicle with the breaker in the TEST or DISCONNECTED position.A circuit breaker is provided in the PTS4 test set to prevent thermal damage from repeated high current tests.

Run Secondary Injection Tests on Trip Units with the Square D S33595

SquareD_S33595The most typical protective devices installed are overload, over current, reverse power, earth fault, differential proportion etc. Injection tests are carried out to check the operation of these protective relays and the breakers. There are two types of injection tests that are normally conducted – primary injection test and secondary injection test. Primary injection test is conducted by injecting the current that is required for the operation of the protective device power through a circuit breaker. The secondary injection test, on the other hand, is conducted when the circuit breaker, though closed is not carrying any current through the main poles.
