Electrical energy has extensive use in our
daily life
Most customers believe that utilities have
caused the problem
Electrical pollution have significant effect
on electrical motor and other equipment
operation
Electenergy Technology Inc. (ETI) of
USA has technology to deal with this
electrical pollution
Introduction
