Tip1:How can we distinguish the quality of the lightning arrester?

1. It can be seen from the reaction time: determine whether the lightning arrester can respond in time and quickly discharge the lightning current.

2. It can be seen from the insertion loss: this refers to the installation of a lightning protector, the impact of this lightning protector on the line, the smaller the better

3. It can be seen from the number of impact resistance: determines the service life of the lightning arrester. Generally, the gas discharge tube will not drop after being placed for a period of time. If you want to check its quality, you can use an adjustable high-voltage DC power supply to test .


Tip2.What skills should lightning protectors have in the selection?
1. Confirm power supply system
First of all, you must determine what your power distribution system is like, whether it is TT, TN or IT system. After determining the power distribution system, you can choose the protection mode and wiring method of the lightning arrester to select the appropriate lightning arrester.
For example, TN-C uses 3P lightning protection device, TN-S uses 4P, TT uses 3P+N, etc.
2. Know the main parameters of the lightning arrester.
