What are the operating regulations for zinc oxide arresters

Manufacturers of zinc oxide surge arresters are generally connected between the wire and the ground and connected to the protected equipment or facilities. They are in an unconnected state under normal conditions. When a lightning overvoltage occurs, the breakdown discharge occurs. When the overvoltage reaches the specified value of the operating voltage , The high-voltage arrester will act immediately to cut off the over-voltage load, limit the voltage to a certain level, protect the equipment from insulation, and make the grid supply power normally. Lightning arresters are mainly used to protect power equipment, and can also be used to prevent high voltage from entering the room, so we must maintain them well during use, so as to ensure our safety during use!                                                                            

The following points should be checked frequently:

1. Whether the wire and ground lead have burn marks or broken strands.

2. Whether the cement joints and the painted paint are intact.

3. Whether the sealing of the lead wire of the upper cap of the 10kv arrester is tight, and whether there is water ingress.

4. Whether the surface of the porcelain sleeve is seriously dirty.

5. Whether the indicator of the action recorder has changed, judge whether the arrester is operating.

6. Whether the porcelain sleeve is complete.

7. Monitoring and regular preventive tests are the only way to ensure the normal operation of the arrester.
