Product Q&A

Q: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

Q:What is the output accuracy of the device?

The device provides an output accuracy of 0.5 magnitude for AC, DC, and voltage outputs.

Q:What is the frequency range supported by the tester?

The frequency range (base wave) supported is from 20Hz to 1000Hz.

Q:What is the maximum three parallel phase current output?

The maximum three parallel phase current output is 0~120A.

Q:What is the warranty period for the tester?

The warranty period is 1 year for the Three Phase Relay Protection Tester.
