What do these statements have in common? • Lightning doesn’t
strike the same place twice. • Electrical utilities correct a
fault by sending a power surge to clear a short in a service
line, transformer or other load grid short circuit. • TVSS
systems will reduce energy consumption by a minimum of 10 to 15
percent. All three are purported to be fact by some people, even
though they run contrary to reality and the laws of nature. The
world is full of folklore about many different subjects, even
about transient voltage surge suppression (TVSS) devices. Ads
for TVSS devices claim that they will solve most power quality
problems, even though sags are typically the most common PQ
phenomena (as much as 60 to 70 percent) experienced in an
industrial facility or residence. This doesn’t seem to affect
the millions of dollars of annual sales of such mitigation
devices. So, perhaps a little knowledge about such may help to
make for “a more educated consumer.” Surge protector products
are primarily designed to eliminate t
