Electrical Surge Protection System Definition

The electrical surge protection system functions as a device that guards electrical equipment against sudden voltage spikes that protect equipment from destructive voltage fluctuations.

Main Components

Surge Protector Unit: The surge protector functions as an equipment protection unit by taking in and redirecting surplus electrical voltage to maintain device safety.
Grounding Wire: Routes extra energy to the ground, which results in effective surge protector operation.
Protective Fuse: Serves as a safety accessory that disconnects the power supply if the system detects unsafe voltage conditions to stop additional system damage.

Other Components

Overvoltage Protector: Guards devices from dangerous voltage spikes above safe operating values to stop the occurrence of high voltage surges.
Overcurrent Protector: Monitors excessive current levels to ensure both overheating and electrical system damage and fire risks are prevented.
Voltage Disturbance Protection: Protects equipment from temporary voltage disturbances that could otherwise damage the system.
