A Primary Injection Kit is a high-performance electrical testing system designed for the testing, commissioning, maintenance, and calibration of current transformers (CTs), circuit breakers, busbars, protective relays, and other high-current electrical equipment. It generates a controlled high-current output by injecting current directly into the primary side of the equipment under test, allowing engineers to verify the performance, accuracy, and operational integrity of electrical protection systems under real operating conditions.
Primary Injection Kits are widely used in power generation plants, electrical substations, industrial manufacturing facilities, utility networks, renewable energy installations, and transmission and distribution systems. They are essential tools for preventive maintenance and acceptance testing, helping to ensure that electrical protection devices operate accurately and safely while minimizing the risk of equipment failure and unplanned downtime.
