TEST-905 5000A primary injection testing of circuit breaker 35KVA in smart grid substation
Primary injection testing is suitable for testing over-current trip relays attached to a circuit breaker. By injecting the current into the system we can measure if the breaker will trip or fail, and how long the current is live before the circuit is broken.
A large current (between 1A and 5,000A depending on system specifications and test requirements) is injected directly on the primary side of the electrical system such as a circuit breaker. The objective of the test is to identify how the system operates under various levels of current load. Primary injection testing is suitable for testing over-current trip relays attached to a circuit breaker.
The primary injection testing is the only way to prove correct installation and operation of the whole protection chain, as involves testing the entire circuit; current transformer primary and secondary windings, relays, trip and alarm circuits, circuit breakers and all wiring are checked.
The MODEL TEST-905 is a powerful primary injection tester capable of testing circuit breakers up to 5,500 amperes frame size. Its primary applications are for testing low-voltage molded-case and metal-clad AC circuit breakers. The unit may also be used for high-current applications such as ratio transformers and heat runs. The TEST-905 runs on 380VAC. This rugged tester has been designed with a focus on durability and ease-of-use.
