Common problems of the relay protection tester: When using the relay protection tester,Relay Tester it is strictly prohibited to plug and unplug the data information cable with power on. Turn off the power of the electronic computer and the detector chassis before connecting the data information cable.Relay Tester When using the relay protection tester,Relay Tester in order to avoid the magnetic induction and electrostatic induction of the shell during the operation of the tester. Before the experiment,Relay Tester the server should be grounded according to the grounding device. When using the relay protection tester,Relay Tester a safety prompt is required when the working voltage above 36V is output. Avoid safety accidents.

When using the relay protection tester,Relay Tester it is strictly forbidden to add the external working voltage and current to the working voltage and current output of the detector. During the experiment,Relay Tester try to avoid the feedback of the external working voltage on the tested protector to the output of the detector And destroy the detector. In order to ensure the accuracy of the detection when using the relay protection tester,Relay Tester the external control circuit of the protector should be cut off. And the N of the working voltage and the N of the current amount are in the same-point common ground. When the relay protection tester is used,Relay Tester the DC stabilized power supply of the relay protection tester can be used as the DC stabilized power supply of the protector,Relay Tester but it cannot be used as the DC stabilized power supply of the actual operation control circuit.
