Introduction:
This Three Phase Secondary Current Injection Test Set is applied to test the relay unit in relay protection system. At the same time it could be considered as a universal three phase AC/DC voltage source or current source.
This Three Phase Secondary Current Injection Test Set is applied to test protection replay based on voltage and current operation.
The main function of 3 phase Secondary Current Injection Test Set: calibration of voltage and current operation relays, secondary circuit inspection,trip value of circuit breaker test, switch on and off time measurement of circuit breaker and so on.
This Secondary Current Injection Test Set is a low cost, simple operation and reliable performance device for secondary circuit test.
Main features:
1. High performance Industrial control computer is adopted as the controlling computer.
2. True color LCD display, tracking ball and optimized keyboard can be used without an external mouse and keyboard.
3. You can access data, communicate data and upgrade software conveniently.
4. The operation is simple and convenient, and is easy to be mastered.
5. High-speed digital controlling processor is adopted as the output core of the tester.
6. High precision D/A converter is adopted for ensuring the precision and linearity of current and voltage in the whole range.
7. Voltage and current amplifier is equipped on the Three Phase Secondary Current Injection Test Set .
8. Digital input and output.
9. Auxiliary DC power supply output for special use is also available with this Three Phase Secondary Current Injection Test Set .
