what causes a power surge in your home how can you fix it
In in some cases, if your home is near a large factory and you share the same transformer or electrical system, even simply powering heavy machinery on or off could cause a surge. A power surge can reach your home, fry your circuit breakers and spread to your outlets. If a device or appliance is plugged in, it may not survive the sudden surge of electricity. So what can you do to make sure your electronics survive an electrical surge? Start with surge protectors, both large and small.
There are many reasons why these surges occur. One of the reasons is lightning which can cause a power surge by increasing electrical pressure by millions of volts. Many electrical devices like air conditioners and elevators that draw a lot of power to switch on and off can also cause power surges. Other factors that can cause a surge may include downed power lines, problem with the wiring, and faulty equipment from the utility company.
And if the power surge is created by a lightning strike or power fluctuation on the utility lines, the service entrance surge protection device can reduce the power surge to a lower level before it gets to the point-of-use surge protection device.
