Customers should ensure they have equipment in place to protect motors and electronics from occasional power surges and low voltage events.
Many businesses, industrial and large commercial customers, even a few homes, have what is known as “three-phase” service. They need electricity, and lots of it.
Customers with big power needs should make sure they have equipment in place to protect three phase motors, such as those found in large well pumps.
Without protection, these motors could be damaged if partial power occurs. One protective device required by the National Electric Code is a single phasing, reverse phasing, or low voltage protector. This protection can be accomplished through the installation of a simple, solid-state apparatus.
Check with an electrician for more information.
These days, it seems that just about any home electronics need to have some form of surge protection. Occasional power surges last only a fraction of a second, but without proper protection, your electronic equipment could be damaged.
The PUD strongly recommends that you use surge protection for all equipment that could be damaged by temporary voltage surges.
What causes a surge in power? There are lots of things including, lightning strikes; a big power user turning high voltage equipment on and off; trees falling across multiple power lines, causing them to momentarily touch; even static electricity in the home can scramble some of the more sensitive equipment.
The most common home electronic products that need protection are computers, televisions, DVD players, stereo equipment, garage door openers, satellite receivers, home security systems, cordless phones, and microwaves and. The owner’s manual will normally let you know if you should use a surge protector.
Some surge protectors offer replacement coverage for equipment damaged while properly plugged into them.
