Abstract
Disturbances on the ac power line are what headaches are made of.
Outages, surges, sags, transients: they combine to create an environment
that can damage or destroy sensitive load equipment. They can take
your system down and leave you with a complicated and expensive repair
job. Ensuring that the equipment at your facility receives clean
ac power has always been important. But now, with computers integrated
into a wide variety of electronic products, the question of ac power
quality is more critical than ever. The computer-based systems prevalent
today can garble or lose data because of power-supply disturbances
or interruptions. And if the operational problems are not enough,
there is the usually difficult task of equipment troubleshooting
and repair that follows a utility system fault. This book examines
the key elements of ac power use for commercial and industrial customers.
The roots of ac power-system problems are identified, and effective
solutions are detailed. The book follows a logical progression from
generating ac energy to the protection of life and property.
