[bkeps.com]Frequency disturbances, transients, grounding, interference…the issues
related to power quality are many, and solutions to power quality
problems can be complex. However, by combining theory and practice to
develop a qualitative analysis of power quality, the issues become
relatively straightforward, and one can begin to find solutions to
power quality problems confronted in the real world. Power Quality
builds the foundation
designers,
engineers, and technicians need to survive in the current power system
environment. It treats power system theory and power quality principles
as interdependent entities, and balances these with a wealth of
practical examples and data drawn from the author's 30 years of
experience in the
design,
testing, and trouble-shooting of power systems. It compares different
power quality measurement instruments and details ways to correctly
interpret power quality data. It also presents alternative solutions to
power quality problems and compares them for feasibility and economic
viability. Power quality problems can have serious consequences, from
loss of productivity to loss of life, but they can be easily prevented.
You simply need a good understanding of electrical power quality and
its impact on the performance of power systems. By changing the
domain
of power quality from one of theory to one of practice, this book
imparts that understanding and will develop your ability to effectively
measure, test, and resolve power quality problems.
