Why Primary Injection Tests?

This type of test involves the entire circuit – current transformer primary and secondary windings, relay coils, trip and alarm circuits, and all intervening wiring are checked. There is no need to disturb wiring, which obviates the hazard of open-circuiting current transformers, and there is generally no need for any switching in the current transformer or relay circuits.

Product Description

Primary Current Injector is essential equipment used for electrical deb ing to generate high current, which be widely used in power plants, power distribution stations, electrical plants , scientific research, laboratories and other units. It is a short-term or intermittent work device and characterized by small size, light weight, good performance, easy use and maintenance.
