Power Sensor Trip Unit Testing with the GE PST1-1 Secondary Injection Test Kit

Posted by Protec Tech Team on

General Electric PST1-1 Secondary Injection Test SetA secondary injection test is a method of verifying the electrical operational characteristics of a circuit breaker. While not specifically addressing components in the primary current path of a circuit breaker, secondary injection testing is used to verify operational settings and characteristics in the decision making portion of the circuit breaker (solid state trip device).  This type of electrical operational testing can be conducted without the need for large, high powered primary injection test equipment. Since this method of testing only uses low level signals that the trip device would normally see from current sensor secondaries, it can also be less time consuming and generally safer than performing primary injection testing.

Secondary injection testing involves disconnecting the decision making portion of the circuit breaker from the VTs or CTs. A secondary injection test set is then used to inject and measure the trip device's operating parameters and performance. If you need a test set for testing circuit breaker trip devices, check out the General Electric PST1-1 Secondary Injection Test Set.

Below are some of features of the General Electric PST1-1.

  •        Can test PS-1, PS-1A-1 and PS-1A used on low voltage circuit breakers AK and AKR circuit breakers
  •        Tests time current characteristics and current pick-up
  •        Can check the Logic component as a separate unit
  •        Can accurately test PSU, Logic Component, wiring and Magnetic Trip while attached to a unpowered breaker
