Introduction to Secondary Current Injection Testing Equipment
Secondary current injection testing equipment is a crucial tool in the electrical power industry. It is primarily used for testing the performance and functionality of current transformers (CTs), protection relays, and other electrical devices. By injecting a known current into the secondary winding of a CT or a protection relay circuit, technicians can verify the accuracy of the device’s measurement, assess its response under different conditions, and ensure its proper operation. This helps in maintaining the reliability and safety of electrical power systems, preventing potential electrical faults and outages. Secondary Current Injection Testing Equipment
