Product Description

Automatic Relay Protection Test System Three Phase Relay Protection Tester

What is the difference between Primary & Secondary injection test?

A primary injection test set injects a multiple of the fault rated current of the breaker, through the breaker while measuring the trip time. The secondary injection test injects a ratio of the fault rated current of the breaker directly into the trip unit and measures how long it takes the breaker to trip. Another way to look at this is a primary injection test tests the breaker as close to a real-world scenario as you can while secondary injection tests the timing and function of the trip unit.

                     secondary injection tester                                                                                                      primary injection tester
 

Introduction:

• GDJB-PC Automatic Relay Protection Test System/Relay and Protection Testing Equipment/Three Phase Relay Protection Tester 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.

• Automatic Relay Protection Test System/Relay and Protection Testing Equipment/Three Phase Relay Protection Tester is applied to test protection replay based on voltage and current operation.

• The main function of the tester include: 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.

• It's a low cost, simple operation and reliable performance device for secondary circuit test.
