Secondary injection testing
Web17 Jan 2024 · The alternative to secondary injection testing is primary injection testing. To do this access to the bus bars is required so that voltages and currents can be applied to the primary circuits. As seen in the diagram on the right, the protection relay (50/51N) takes current from 1600:1A CTs. WebThe patented CPC 100 primary injection test system replaces several individual testing devices. This reduces the costs for training and transport, and cuts down testing time. …
