Power Surge

What is a power surge? Here’s What To Do When It Happens

The world and our lives are run by computers, appliances, and other electrically powered systems. Any disruption or damage to these electrical devices caused due to power surges can interrupt the progress of our lives. Therefore, it is important to protect these devices against power spikes.

What Happens During a Power Surge?

Surges in electrical power happen when the supply of electricity is higher than usual. A power surge occurs when significantly more voltage is sent through wires to devices. Surges can be small or large, resulting in decreased performance or damage to plugged-in devices.

Causes of Power Surge

There are several reasons due to which it can happen. These can be:

  • Electrical overload
  • Faulty and defective wiring
  • Lightning strikes
  • Overworked electrical circuits
  • Large electrical appliances
  • Transformer malfunction
  • Restoration after blackout or power outage

Power surges can fluctuate from one volt over the threshold maximum to hundreds of excess volts. No matter on what scale the power surge happens, they have the potential to damage any electrical device and its internal components. Probable signs of power surges on your electrical devices may be:

  • Appliances or devices are not functioning or are powered off.
  • Flickering of lights and digital clocks.
  • Power strips and surge protectors may need to be reset.
  • Outlets or surfaces around wires experiencing discoloured or scorched
  • Burnt odour near the power plugs, switches, and electrical devices.

Dealing with the After-effects of Power Surges

The very first thing you should do if your property or appliance has had a power surge is not to panic. Follow the steps to safeguard other appliances from further damage:

Reset & Repower the Appliances

If the surge has caused a power failure, unplug all devices and reset them before resetting the electrical circuit breakers.

Examine the Damage

Check all your electronic equipment and appliances for damage and make sure they don’t constitute a fire hazard. If lightning, water, or a downed power line caused the power surge, inspect your property carefully for any issues. Alternatively, you can call an expert to assess your home for any damages and other electrical dangers. Check to verify if your devices are still working by turning them on and off one by one.

Inspect the Heating, Ventilation, and Air Conditioning (HVAC) Units

After a power surge, thoroughly inspect your property’s HVAC unit for electrical damage. If the HVAC unit is shut down, reset it following the manufacturer’s manual. If you don’t have the instruction manual or are concerned about the safety of your system, call a professional to reset the unit or contact the manufacturer for support.

Takeaway

Power surges are common, and if you do not take the necessary precautions, they can pose damage to your family and property. Consult trained electricians at R. A. Pearson Electrical to install power surge protectors on sensitive and high-end electrical systems for overall protection. They offer residential as well commercial electrical maintenance services.
