Everyone knows that now is the era of intelligent electronic information technology with relatively advanced high-tech technologies. There are more and more household appliances and various new technology equipment that everyone uses. There are safety risks for so long, especially in rainy seasons, when lightning and thunder are also the case. 

This problem can be solved by having a lightning arrester, and power lightning arresters are more common in daily life, but there are still many people who don’t understand how the power lightning arrester should be wired when they just touch it. , So that everyone can use the power surge protector more strongly, the following editor will introduce how to connect the power surge protector for everyone:

Power lightning arrester connection method: In the TN style, under normal circumstances, the power lightning arrester only needs to be connected to the common mode wiring method, that is, it is connected between the neutral point of the live line and the protective grounding line. But at the start and end of the TN-S style, there is no need to connect a surge arrester between the neutral point and the protective grounding wire. Differential mode connection is only required for the switch power supply port numbers of the third and fourth levels of the A-level lightning protection level and the third level of the B-level lightning protection level. Power lightning protection device in the middle of neutral point.

In the TT style, when the first-level power lightning arrester is located behind the power protector, the common mode wiring method can be used. When the first-level power supply lightning protection device is located before the power supply protector, and the high-voltage system software is the positioning point grounding protection, the switching power supply protector needs to use the "3 1" wiring method, that is, the three live zero wires are to the neutral point Connect a switching power supply protector for each, and connect a switching power supply protector for the neutral point to the protective grounding line. In the IT style, the power surge protector is only used for common mode wiring.
