Arrester Discharge Counter Detector

Arrester Discharge Counter Detector

Type: ZC-713
    ZC-713 arrester discharge counter test instrument used to verify the reliability of various arrester counter action. The reliability of counter action is very important to the power system. It is an important parameter to record the frequency of lightning in the normal operation. It can provide an important basis for the electric power system to provide a specific test for the arrester. This instrument is mainly used for high voltage lightning arrester above 35kV.

Product Features
    1. The output end of the instrument is connected with both ends of the arrester counter, the red end is connected with the upper end, and the black end is connected to the ground.
    2. After the power cable is connected, check the instrument and the wiring is correct, and then start the test after the confirmation.
    3. Close the power switch (power light), to be stable voltage (1000V), you can begin to check.
    4. By pressing the measuring key, the output voltage drops immediately, and the action of the counter can be observed.
    5. For multiple tests, when the output voltage to achieve stable value, and then press the check key, and observe the action of the counter.
    6. After the test is completed, immediately turn off the power supply, the output voltage is completely zero, to remove the connection.
    7. If the key is pressed, the output voltage is not decreased, the power should be turned off, after the voltage is zero, check whether the circuit has a breakpoint, or discharge counter is not suitable for the technical specifications of the model.
