The relay protection tester (also known as: relay protection detector) can do most of the relay protection test of electrical appliances,Relay Tester such as working voltage, current amount,Relay Tester middle, time, output power orientation,Relay Tester current period, frequency, characteristic impedance,Relay Tester Common electrical relays such as overcurrent. The common problems of the relay test of the relay protection device detector are as follows: the relay protection device detector,Relay Tester the final value of the overvoltage relay and the initial value of the undervoltage relay can not be too large,Relay Tester to prevent the incorrect contact from causing the working voltage to rise and burn the car relay .

During the whole process of detection, two kinds of conditions should be set again. For example,Relay Tester when the initial value is in the posture, when the final value is not in the posture,Relay Tester the undervoltage relay and the current relay may encounter the above situation and may be set again. The final value of the current relay must not be too large to prevent the incorrect contact from causing the current to increase and burn the car relay. When detecting the final pressure lockout, the voltage of each phase should be set to 0.95 times, 1.0 times,Relay Tester 1.05 times of the bottom pressure lockout time,Relay Tester etc., and output at different rates, and observe whether the protector is posture locked.
