Injection Test: What are Primary and Secondary Injection Tests?

WebbA primary injection test is helpful for substations or circuits with high voltage and current. It is just the flow of rated current in the circuit under test. If the rated current of the circuit is 2000 A, then 2000 A of current must flow through the circuit. This is necessary to verify overall equipment health and protection system performance. WebbThe DDA-1600 circuit breaker tester incorporates proven transformer design with the latest development in high current instrumentation and control. This new design means the DDA-1600 is fully compliant with NEMA AB-4 test guidelines. Ideally suited for industrial, utility, and testing service company use, mims contractors https://bneuh.net
