Secondary Injection Test Solutions – SMC
Secondary injection test and primary injection test, the two sides of the coin. The secondary injection test may involve the testing of individual components, such as the important relay testing, but it is also essential to test the entire protection circuit, from beginning to end, which is preferably performed with primary injection testing, which also tests the CT/VT ratios, polarity and …
Primary injection test systems – Megger
Primary current injection testing is utilised in high current/high voltage scenarios found at large electrical installations such as substations. A large current (between 100A and 20,000A depending on system specifications and test requirements) is injected directly on the primary side of the electrical system such as a circuit breaker.
Primary vs. Secondary Injection Testing for Circuit Breakers
Mar 14, 2017· Because primary current injection testing is a relatively expensive service, it’s usually performed only during the commissioning (start-up) process to supplement a program of periodic secondary-current testing. Circuit breakers that are part of a critical process or engineered safety system are often maintenance tested using primary injection …
