Our homes are filled with expensive appliances and electronic devices that run on electricity. Power surges can harm these items to the point they cannot function anymore. Fortunately, whole home surge protection can be installed to guard against the negative effects of power surges. Consult with an experienced and licensed electrician for the best results.
Power Surge Description
Also called voltage surges, power surges occur when voltage rises beyond what is normal for a period longer than 10 milliseconds. They can be categorized by two types:
1) Spikes, also called elevations, or interruptions of electrical current result in a jump in the energy flowing to electrical outlets.
2) Electrical sources inducing energy backflows.
Depending on the cause, a power surge can suddenly raise the flow of electric current from just five volts to thousands of volts. Considerable variations in electrical flow are capable of frying electrical equipment plugged into outlets while completely blowing fuses. Power surges can harm the expensive items below:
• Entertainment systems, including TVs, stereos, and Blu-Ray/DVD players
• Computers, servers, and peripheral equipment including routers and printers
• Appliances, including refrigerators, microwaves, washing machines, dryers, and dishwashers
• HVAC (Heating, Ventilation, and Air Conditioning) Systems
• From 50 to 100 energy spikes strike an average home every day.
• During colder seasons, energy demands rise, resulting in a greater risk of damaging power surges.
• Lightning strikes are often not covered by home insurance policies.
• Sensitive equipment can even be damaged by lightning striking within a mile.
Lightning occasionally strikes power lines or transformers, causing a jump in voltage. Other power surges occur when falling tree branches or flying debris collide with utility lines, when electricity is restored after power outages, and when there is a transfer of electricity carried out by the power company. However 60% to 80% of all home power surges are caused by appliances and air conditioning systems cycling off / on .
