I. Introduction:
PCi series primary current injection tester is applied in power system for circuit breaker test, protection system test and current transformer test. The current injection test kit generates a high current from power supply to simulate the rated current or fault current in the primary circuit of power equipment.
The 1000A/15KVA primary injection test equipment is designed in integrated model.
Funtions and features:
1) High current output is injected to the main circuit of power line to simulate the fault current. And then check whether the protection system will be operated according to the design.
2) High current output is injected to the primary of current transformer and then measure the inducted current from secondary by error measurement instrument to check the ratio error and phase displacement of CT.
3) High current output is injected to the main circuit of circuit breaker to simulate the rated current in primary. And then check the stability of circuit breaker according to the temperature rise procedure.
4) This primary current injection test kit is considered as a AC high current source in power equipment or cable test.
5) It's characterized as polar-less adjustment of output current, stable increase of current, large scope of load variation, reliable function, easy and safe operation and etc.
6) The primary current injection test can be taken as current source equipment for current/temperature increase of industrial and mining equipments.
