Primary Current Injection Tester System with Circuit Breaker Timer

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 set 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 system is designed in integrated model.

Features:

1 High current output injected to the main circuit of power line to simulate the fault current. Then check whether the protection system will be operated according to the design.
2 High current output 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 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 This primary current injection test set is also considered as a AC high current source in power equipment or cable test.

5.Current is measured from the secondary of current transformer which is installed in the internal of the current booster.
