Have you ever experienced a power flicker instance and on trying to switch on your TV or the refrigerator, they adamantly refuse to turn on, and you wonder what has gone wrong. They have been blown out by the excess voltage in the electric lines which caused the flicker.

Electricity is such an important catalyst for smooth flow of the majority of the home and business operations. The same level of usefulness equally weighs the same degree of risk electricity carries. One of the major risks and the primary cause of electrically related loss is the power surge.

A power surge is an overvoltage in your electric line. Since a power surge carries a high level of voltage, it can destroy and blow out most of your electrical types of equipment since they have a limited capability to handle unlimited energy levels.

The worst part of the losses resulting from these electric power surges is that a general home insurance policy does not cover it.  Thus, unless you are more informed or makes the relevant inquiry, you won’t have your home covered by the insurance.

What Causes electric power surges.

  • They can happen during power switching phases from the main utility company distribution center.
  • Devices with a motor shut on or off diverting voltage to or from other electrical appliances.
  • Lighting and heavy storms which can cause a short circuit in the power lines.
  • If two electric wires touch each other.
  • Build up of energy in a system and being released at once.

Protect your home from power surges by taking the following actions.

Use voltage surge protectors

They resemble the regular power strips and serve the same purpose but at an enhanced level. These act as the gatekeepers to your electric system, when they sense overvoltage, they immediately redirect the excess voltage to the ground through the earth wire. They are a bit more expensive than the ordinary power strip.

Surge suppressors

These are installed at the electric panel or switches, and they ensure that the excess voltage does not get into your system in the first place. These suppressors should only be installed by a qualified electrician since the electric panel controls all the power supply in your home.

Ensure you switch off electrical appliances during the times of power outages and only switch them on when the power is back.

Use GFCI (Ground fault circuit interrupters) outlets which act as super sensitive circuit breakers. If these outlets sense that the incoming and outgoing current are not of the same voltage level, it will automatically shut itself off and cut the power in the system.


Power surges can occur in two types

The voltage surge– This lasts longer up to 15 milliseconds.

The power spike- Last for a shorter period but carries a very high voltage.

Thus, it means the effect of all these power surges is the same, and same precautionary measures apply in both instances.

You can do a whole house power surge protection by installing suppressors both at the main circuit breaker panel and use of power strips which are surge protection enabled.
