Surge protection devices (SPDs), also known as lightning protection devices, is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines. When the electrical circuit or communication line suddenly produces a power surge due to external interference, the surge protector can conduct the shunt in a very short time, thus avoiding the damage to other equipment in the circuit.

A power surge is basically a spike in your home's electrical current. The spike is very brief, usually lasting less than a thousandth of a second, but it can still cause damage to your home and appliances. A power surge can damage or destroy home appliances, and in a worse case scenario, start a house fire.

These are some of the top causes of power surges:

  • Lightning storms
  • Turning high-powered electrical divorces off and on rapidly
  • Downed power lines
  • Damaged or faulty wiring

Principle of SPD

SPD is designed to limit transient overvoltages of atmospheric origin and divert current waves to earth, so as to limit the amplitude of this overvoltage to a value that is not hazardous for the electrical installation and electric switchgear and controlgear.
