Working Principle Of Surge Protector
- Apr 17, 2018 -

Surge protector is an indispensable device for lightning protection of electronic equipment. It used to be called "surge protector".

The effect of "lightning arrester" or "overvoltage protector" in English for SPD. surge protector is to limit the transient overvoltage to the power line, the signal transmission line within the voltage range that the equipment or system can bear, or to inflow the powerful lightning discharge into the ground, and to protect the protected equipment or system from being damaged by the impact.

The type and structure of surge protector are different according to different uses, but it should contain at least one nonlinear voltage limiting element. The basic components for surge protector include discharge gap, gas discharge tube, varistor, suppression diode and choke coil.
