Surge protective devices, also known as lightning protectors, with the application of various advanced information systems such as computer communication network systems, many electronic devices are operating under the state of voltage and small current.
The EMC capability, lightning electromagnetic pulse resistance, overvoltage, and overcurrent capabilities are very fragile, so the vulnerability in lightning environments is high. When lightning arrester is installed, the surge protector can conduct shunt in a very short time to avoid the damage of surge to other equipment in the circuit when the electrical circuit or communication line suddenly generates peak current or voltage due to external interference.
