The relay protection tester is usually used in accordance with the instruction manual or the system is not trained when it is purchased. In this way, you will always be at a loss when you encounter difficult problems. Let's use the specific method of relay protection!

1. Wiring instructions

The yellow, green, red and black wiring terminals on the panel of the relay protection tester are the voltage output terminals of the instrument. The back of the panel has DC output and power connections. There is a grounding jack next to the power jack to facilitate the tester to ground the equipment.

Demo:

After turning on the power of the instrument, turn it on. According to the color of the coil, connect the terminal of the corresponding color. For example, the black coil is inserted into the black jack of the current output of the relay protection tester, and the other end is connected to the relay. Do the corresponding wiring operations in the same way for other colors according to the corresponding parameters and colors. Then use a multimeter to test whether the wiring is successful.

2. Operation demonstration

Adjust the current amplitude and amplitude step length according to the current phase of your own terminal. Single-phase test does not need to set the phase. For other phase tests, you need to adjust the phase, and then set the phase step. Adjust the test type to your own test type (manual or automatic) and start the test. During the test, when you hear "bell~", turn the button to "stop", and then get the test action time. If you need to increase the test time, just adjust the amplitude step.

3. Output detection of AC voltage and AC current

After Z, remove the test wire and use a multimeter to detect the output of current and voltage, return the interface to the parameter setting interface of the AC test, and set the voltage amplitude, amplitude step length and other parameters first, and then use the multimeter head to test the operation panel The voltage output. Immediately adjust the current amplitude, amplitude step, etc., switch the multimeter to the AC gear, plug the multimeter head into the current output of the panel, and turn the button on the panel of the relay protection test instrument to start the test. Observe whether the multimeter is in line The current on the instrument is consistent and the test is completed.
