Primary Current Injection Tester HYPCIT
HYPCIT series primary current injection tester is applied in power system for circuit breaker test, protection system test and current transformer test. The current injection tester generates a high current from power supply to simulate the rated current or fault current in the primary circuit of power equipment.

Contact Us1) The high current output is injected into main circuit of the running line to simulate the fault current, and then the protection system can be tested whether it will be operated according to the design.
2) The high current output is injected into the primary side of the current transformer, and then the induced current is tested from the secondary side by an error measuring instrument to detect the current transformer ratio difference and phase shift.
3) High current output is injected to the main circuit of circuit breaker to simulate the rated current in primary. Then check the stability of circuit breaker according to the temperature rise procedure.
4) It is considered as a AC high current source in power equipment or cable test.
1. Power supply: AC220V or AC 400V, 45Hz~65Hz.
The power supply voltage depends on the power output capacity. Detail information is as table 1.
