Secondary System and Relay Protection Testing Technology
Secondary injection testing is one technique to test protection relay functionality without powering the main electrical equipment. Rather than passing real current through cables and transformers, test equipment injects exact signals directly into the relay's secondary terminals. Why done prior to primary injection tests? This is. At EuroSMC, we specialize in providing state-of-the-art relay test sets and solutions for comprehensive relay testing and secondary injection tests. This test is often performed during commissioning, periodic maintenance, or after relay repair. By mastering both Primary Injection Testing.
