3kV Zinc Oxide Lightning Arrester Discharge Counter Tester

I.Overview

Lightning arrester is an important electrical equipment in power network to protect power equipment from over-voltage. Normally, the action of the arrester and leakage current are monitored through the arrester monitor. Due to poor sealing, the monitor may enter water or moisture during operation, causing internal element corrosion, or other reasons, the monitor counter cannot operate normally, and the leakage current indication is not accurate. Therefore, according to 《The Regulations》, the arrester monitor should be checked once a year。

The reliability of counter operation is very important for power system. It is an important parameter to record the number of lightning strikes received by the arrester in normal operation. It can provide an important basis for the power system workers to inspect the arresters.

Operation Method

Schematic diagram of detector panel

1. Connect the output end of the instrument with both ends of the arrester counter (the connecting line should be as short as possible), connect the red end to the upper end and the black end to the ground end.

2. After the power cord is connected, check whether the instrument and wiring are correct, and then start the test.

3. Start the power switch, and the voltage will rise. Generally, the counter can start checking when it is around 600V.

4. Press the check key and the current voltage is output. At this time, the action of the counter can be observed.

5. If multiple tests are needed, press the check key when the output voltage reaches the required value and observe the operation of the counter.

6. Turn off the power immediately after the inspection, and remove the connection only when the output voltage returns to zero.

7. If the output voltage does not decline after pressing the check key, the power should be turned off. 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.
