What is surge protection and how does it work?

Surge

A surge protector is a device which is designed to prevent voltage spikes from entering the equipment that is plugged into power points within your home or office. It attempts to limit the voltage supplied to an electric device by either shorting or blocking the unwanted voltages to ground. The most common electrical surge comes from lighting strikes.

 

In some countries where electronic gadget is used, the effective AC application voltage is a hundred and ten to one hundred twenty volts; the peak voltage is on the order of plus-or- minus a hundred and sixty to one hundred seventy volts at a frequency of 60 hertz. But transients, which stand up from diverse causes, typically attain top tiers of numerous hundred volts. Those pulses are of brief duration, measured in microseconds, however in that point; they could lead to hardware malfunctioning.

 

Equipment that can have its hardware malfunction during a surge include computers, laptops, ovens, air conditioner units, pool pumps and TVs. The worst kind of transient occurs while lightning strikes the area. Such a ‘spike’ can height at lots of volts and can cause permanent damage to equipment.

 

There are two types of surge protectors that are commonly used. The Main ‘coarse’

protector can be used in isolation, and the ‘fine’ protector can be used in conjunction

with the ‘course’ protector.

Main ‘Coarse’ Protection

This device is ideally suitable for domestic dwellings and offices. It protects your lights,

PowerPoints and switchboard from electrical surges like a lightning strike. Items

plugged into power points are also protected, like your computer, entertainment

equipment, ovens and reverse cycle air con units and pool pumps.

‘Fine’ Protection

This device has low to medium diverting capacity and has exceptionally fast response

times. It gives added security when protecting all your valuable items that are plugged

into power points around your home and office. You cannot use a ‘fine’ surge

protector in isolation, it needs to have a main ‘course protection installed first.

 

Insurance companies vary as to if your insurance will cover the loss of all of your

appliances and equipment in the event of a power surge. Some insurance policies

specify that you are required to have surge protection installed.

 

Only licensed electricians can install surge protectors.

 

 

We highly recommend that our clients install both the ‘coarse’ and ‘fine’ surge

Protection.
