Q: How surge protector works

A: Surge protector diverts the excess voltage and current from transient or surge into grounding wire and prevents it from flowing through the electrical and electronic equipments while at the same time allowing the normal voltage to continue along its path.

 This excess energy can cause damages in electrical and electronic equipments, process control instruments-equipments.

Two main functions of the surge protector are :

1. Provides low impedance path for conducting a lot of current to eliminate the extra voltage.

2. Absorbs and diverts the extra current to ground for protecting the effects of transient or surge.
