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.
