Power lightning protection includes power lightning protection module, power lightning protection box, power lightning protection socket, etc.
The difference between power lightning protection module and power lightning protection box is the difference in size, the latter is more powerful and has a lightning counter, etc., but the module is easier and cheaper to install than the lightning protection box. [1]

By use
(1) Switching type lightning protector
Its operating principle is when there is no transient overvoltage presented as a high impedance, but once the response to lightning transient overvoltage, its impedance is suddenly changed to a low value, allowing the lightning current to pass. Devices used for such devices are: discharge gaps, gas discharge tubes, gate transistors, etc.
(2) Voltage limiting type lightning arrester
Its working principle is that when there is no transient overvoltage for high impedance, but with the increase in surge current and voltage impedance will continue to decrease, its current-voltage characteristics are strongly non-linear. Devices used for such devices are: zinc oxide, varistors, suppression diodes, avalanche diodes and other lightning protection devices are mostly voltage limiting type.
(3) shunt type or choke type lightning arrester
Shunt type: parallel connection with the protected equipment, the lightning impulse is presented as low impedance, while the normal operating frequency is presented as high impedance.
Choke type: in series with the protected equipment, the lightning impulse presents a high impedance, while the normal operating frequency presents a low impedance.
