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.

Lightning protector is used to protect various electrical equipment in the power system from lightning overvoltage, operating overvoltage, frequency transient overvoltage impact and damage to an electrical appliance. The main types of lightning arresters are protection gaps, valve-type lightning arresters and zinc oxide lightning arresters. Protection gaps are mainly used to limit atmospheric overvoltage and are generally used to protect incoming sections of distribution systems, lines and substations. Valve type lightning arresters and zinc oxide lightning arresters are used for substation and power plant protection, and are mainly used to limit atmospheric overvoltage in 500KV and below systems, and will also be used to limit internal overvoltage or as backup protection for internal overvoltage in ultra-high voltage systems.

Surge protective device, protect against lightning surge voltages in solar system (photovoltaic

power supply system).

These units must be installed in parallel on the dc networks to be protected and provide common

and different modes protection. Its installed location are recommended at both ends of the dc

power supply line (solar panel side and inverter/converter side), especially if the line routing is

external and long.
