Small LED Light As Indicator In A Surge Protector
However, the most beneficial advancement of late is that small LED
bulbs are now utilized as indicator lights in the device that protects
equipment from power surges, the surge protector. Surges, otherwise
called voltage spikes or transient surges, are abrupt increases in
household voltage what happen when high-energy appliances or computers
are powered on. Such surges can take place in excess of 2,000 times
per year in homes, slowly destroying the components of a home

===== Is this sentence true. Many times a year? And more
importantly, *slowly* destroying. Not ruined or "no damage"?

Many times a year - sure. How big a surge counts? Do they count surges
that can do no damage? Yes.

Slowly deteriorating? Can happen. Mostly hype.

Manufacturers don't publish specs, but equipment is likely to have a
surge immunity of about 600 or 800V.


computer, a cell phone, and other fragile electronic equipment. Other
home appliances, furnaces, air conditioners, washers, dryers, and the
like, are also know to create surges which travel back through the
main breaker panel and out again through the home wiring.

Some devices, like motors when shut off, can create surges. Not likely
to damage anything. More hype.

Surges damage cell phones? I would ignore anything this source says.

An excellent source of information on surges for the general public is:

For the more technically inclined a better source from the IEEE is:
