Lightening strikes on a building can generate a surge in electrical power or transient voltage. This lightning power surge can damage electrical devices that are plugged in at the time of the strike. This can cause considerable damage to electrical and electronic systems and equipment, leading to serious disruption and expense to the business premises in question.
Electrical surges can damage computer equipment by burning wires or wearing down the device’s internal components and may even wipe out data saved on the IT system.
Surge protectors can also protect telephone and cable lines which also carry electric current.
A surge protector works by channelling the extra voltage into the outlet’s grounding wire, preventing it from flowing through the electronic devices while at the same time allowing the normal voltage to continue along its path.
