A power surge is basically a spear in your home’s electrical current. The spike is very brief, usually lasting less than a thousandth of a second, but it can still cause damage to your home and appliances.
5 REASONS OF POWER SURGES
Lightning strikes are a common cause, but most power surges stem from inside your home. Power surges occur when the flow of electricity is interrupted, then started again, or when something sends electricity flowing back into the system
1. Overloaded Channels or Circuits
Survey the outlets under your desk, behind your television set, or anywhere else you have a warped web of wires. Plugging in too many usages or electronics in the same socket can lead to power surges and electrical fires.
If you are facing power surges, have an electrician check to see if all of the outlets in a room might be operating on the same circuit. If so, overloading one outlet might not be the problem. The circuit itself may be overloaded trying to power too many usages in the same room.
2. Damaged or Uncovered Wiring
Troublesome little critters such as mice or collectors can chew on the wiring inside the walls of your house or building causing the wiring to fail. Damaged or uncovered wires can cause power surges because the electricity fluid through them is not being directed or handled in the way it normally should.
If wires are damaged, you may even smell smoke as the wires can melt or burn up due to the unusual flow of voltage. Note that uncovered wires should not be handled as they can cause electrocution. Instead, consult an electrician who can test and replace the affected outlets and wires as needed to ensure safety.
3. Lightning Strikes
Lightning touching down simply near your power line can lead to an extra thorn in electrical voltage of millions of volts. That’s why your cable box, lamp, or computer do not stand a chance against a power surge caused by lightning strikes, unless you are using a surge protector. During especially severe storms however, it may be best to power down and unplug expensive equipment.
It is also originate inside a home when large appliances like air conditioners and refrigerator motors turn on and off.
Power surges from lightning strikes can destroy your electronics causing them to fail to power back on. This can be an expensive and annoying problem. For a business this can lead to data loss, or the need to replace costly equipment.
4. High-Power Electrical Devices
High-energy usages or machines like elevators, refrigerators and air conditioners can cause energy spikes and power surges. That is because when they power on they tend to draw an unusually large amount of electricity and that additional power courses throughout the circuit, uncontrollable other usages and electronics in its path. When this happens it is common to notice the lights flaming or flashing off and on in your house or workplace.
5. Power Outages
Ever notice how momentarily bright all your lights get when they first come back on after a power outage? The idea that a power outage can cause a power surge seems counter-intuitive. However, that massive burst of energy that turns the power back on for a whole neighborhood, town or state may lead to excess energy coursing through the lines.
HOW CAN I PROTECT MY PROPERTY?
Point-of-use surge protection devices (SPDs), combined with a good grounding system, should protect your electronic and electrical usages from most electrical surges. An SPD does not suppress or arrest a surge; it actually diverts the surge to the ground.
One familiar point-of-use surge suppressor looks like a regular plug strip. However, unless it specifically says so, don’t assume your plug strip offers surge protection.
You can also install special electrical outlets that offer surge protection. Surge protection outlets are useful in locations where there isn’t room for a plug-in surge protector, such as near a countertop microwave oven.
