The English abbreviation for surge protector is SPD. In the lightning protection work of building electrical systems, the surge protector plays a vital role. It achieves the limitation of transient over-voltage and shunt surge current. Building electrical protection. The surge protector consists of discharge gaps, diodes, filters, and varistors. Depending on the application, the types of surge protectors are different. They can be divided into power line surge protectors and signal line surges. Protector, etc.
This article will provide an in-depth introduction to the selection principle of surge protectors, clarify the settings of surge protectors in low-voltage power distribution systems, and, in addition, explain some of the issues that should be noted when installing surge protectors.
