Power Quality and Reliability is the key to successful delivery of quality
product and operation of an industry. It is now even more critical to the industry
because of increasing application of electronic loads and electronic controllers
which are sensitive to the quality of power supplied. These can have serious economic
consequences and cost business millions of rupees each year in revenues loss, process
improvements, and scrapped product. There is a dire need for all concerned to discuss
the business of power quality and the latest technologies for improving power system
efficiency and reliability.
The proliferation of computers and other sensitive devices throughout our manufacturing
and office environment has fostered the need to design the electrical systems of
buildings and industrial establishments with an eye toward power quality issues.
Poor power quality affects the reliable operation of machines, systems, automation,
equipments, processes and computer-based equipment, which are now so ubiquitous.
Often more important than the physical effect on the equipment is the loss of productivity
resulting from equipment failure, mis-calculations and downtime. The vast majority
of power quality problems in any installation originate within the same establishment
or utility. The most serious consequence of poor power quality, frequently, is not
the physical hardware that may be damaged, but the lost data, reduced productivity,
costly downtime and poor product quality. Like most ailments, they are much easier
and cheaper to prevent than to diagnose and cure.
The Institute of Electrical & Electronic Engineers (IEEE), various government agencies
and other organizations have been studying these problems and effects for several
years. As a result, they have issued design guidelines and recommended practices
that are known to greatly mitigate, if not eliminate, the incidence and severity
of power quality related problems.
There are a variety of techniques that can help prevent or alleviate the effects
of poor power quality. Amongst others, the simple solution is to involve better
electrical designs and installation of additional wiring. These techniques are inexpensive
to install, especially when an installation is undergoing construction, and they
may also be cost effective during retrofits.
APQI, or the Asia Power Quality Initiative, is a joint effort of the International
Copper Association (member of Copper Alliance), the Electrical and Electronics Institute
(Thailand), the University of Bergamo (Italy) and other prominent organisations
from Indonesia, Malaysia, Philippines and Vietnam. We were established in 2008 with
financial support from the European Union’s Asia-Invest programme.
