3kV Zinc Oxide Lightning Arrester Discharge Counter Tester
I.Overview
The lightning arrester is an important piece of electrical equipment in power networks, designed to protect power equipment from overvoltage. Under normal conditions, the action of the arrester and its leakage current are monitored through the arrester monitor.
However, due to poor sealing, the monitor may allow water or moisture to enter during operation. This can cause internal element corrosion or other issues, leading to counter malfunction and inaccurate leakage current indications. For this reason, according to The Regulations, the arrester monitor should be inspected once a year.
The reliability of counter operation is critically important for the power system. The counter records the number of lightning strikes received by the arrester during normal operation, providing an important basis for power system personnel to inspect arresters and assess their performance.

Connection – Begin by connecting the output end of the instrument to both ends of the arrester counter. The connecting line should be kept as short as possible to minimize interference. Connect the red end to the upper terminal and the black end to the ground terminal.
Pre-Test Check – After the power cord is connected, carefully check whether the instrument and wiring are correct. Only then should you proceed with the test.
Power On and Voltage Rise – Start the power switch, and the voltage will begin to rise. Generally, the counter can start checking when the voltage reaches around 600 V.
Checking Operation – Press the check key to output the current voltage. At this point, the action of the counter can be observed to verify proper operation.
Multiple Tests – If multiple tests are needed, press the check key when the output voltage reaches the required value and observe the operation of the counter each time.
Post-Test Shutdown – Turn off the power immediately after the inspection is complete. Remove the connection only when the output voltage has returned to zero, ensuring safe disconnection.
Troubleshooting – If the output voltage does not decline after pressing the check key, turn off the power. After the voltage indicator returns to zero, check whether there is a break point in the loop or whether the discharge counter is not suitable for the model specified in the technical index.
