This powerful test system is designed for primary injection testing of protective relay equipment and circuit breakers. It is also used to test the turns ratio of current transformers and for other applications that require high variable currents.The instrument automatically collects, analyzes, stores and prints test data, and indicates the precise test time and printing time. It can also be copied out with a U disk, so it can be stored as the original test data. The product has large output capacity, small size, light weight and full functions, which is very suitable for CT field test and calibration of various specifications.
