Power Surge Diverters and How This can Protect your Assets during a Power Surge


Share On:


A power surge happens when there is a sudden boost of electrical charge at any point of the power lines.

 It can originate from inside and outside your homes. For surges originating from outside, the usual causes are the following:

  • Lightning

Lightning during storms is so powerful that a simple strike at the power lines will result in spikes of a million electrical voltages. Earlier this week, the coastal part of New South Wales and Newcastle has experienced fierce storms that left many homes and properties without any electricity for several days.

  • Fallen trees and animals

Fallen trees and animals such as possums, bats, birds, and even snakes cause a shutdown when they come in contact with the power lines, transformers and fuses.

Last February 22, 2018, bats caused a high voltage power surge in Maryville, Islington and Wickham. The Plumbing and Electrical Doctor offices received many calls from customers asking for help to fix their electricity fast. We had to enlist the help of our partners to help out. When the power returned, several found that their appliances refused to work. The bats did not only knock-out the electricity in the area, but the blackout also short-circuited several electrical assets.

For power surges happening inside your home or property, big electronics and appliances such as refrigerators and air conditioners can cause this. Unlike external power surges, the internal ones do not cause immediate damage to your property. However, it causes gradual damage to your appliances and electronics that would put you at risk in the long run. 

What can you do in the event of a power surge?

We cannot prevent a storm from carrying debris and pushing falling trees to the power lines or stop bats from making a temporary stop in our transformers and fuses. However, this should not stop you from safeguarding your assets from damage and property loss.

A popular mechanism that you can use is a power surge protector. They usually look like power strips. Unlike power strips, surge protectors come with a built-in feature that controls the voltage that flows into your devices and cuts it out when a surge happens. The packaging of these products also come with the number of Joules that can be absorbed. Surge protectors can protect small devices like your computers, home theatre systems, televisions and phones from short-circuiting and overload.

However, if you want a mechanism that can shield your whole property and all the appliances that come with it from a power surge, you will need a surge diverter. A surge diverter protects all the appliances in your home, including the wiring and fuses underneath your walls. It acts as a whole house power surge protector. 

How does a surge diverter work?

The surge diverters “divert” extra electricity to the ground and away from your electrical circuits. This act prevents electrical damage to electronics and appliances, especially those that have sensitive microchips. A licensed electrician should install a surge diverter on your circuit board so all devices plugged into your power supply are protected in times of power surge.
