Use power distribution systems to improve profitability and competitiveness.

Most plant power distribution systems have been in place for a long time. During the intervening years, technological advances have wrought many changes to what once was considered normal operation. It’s no longer true that across-the-line motor connections are the norm, nor is incandescent lighting the only option available. Modern plant hardware is replacing older equipment in an effort to reduce the rising cost of utility bills. Some plants have even gone so far as to generate some of its own electrical power to permit partial and even complete disconnection from the grid. Also, variable-speed drives are being used on more than air compressors. The bottom-line goal of all these measures is to improve profitability and competitiveness. In some cases, it might be appropriate to revamp the plant’s power distribution system to achieve a better match between it and the connected equipment’s power requirements.

The ubiquity of digital control systems and the necessity to keep them operating at all costs might render a backup power system as a mandatory adjunct to a legacy electrical distribution system. Some plants install permanent power monitoring equipment on various electrical loads to gain better control over demand charges and to provide the feedback that is needed to document instantaneous consumption. It’s the maintenance professional who is on the front line in the care of power distribution systems. These are the people who have most to lose if high-voltage lines cause problems. It’s no wonder that safety has become an important consideration in recent years.

One of the main underlying motivations for this situation is the financial aspect of avoiding the chaos that follows a major accident. The cost of an arc flash incident includes the injury, and the worker’s compensation claims and changes in the insurance rates, and the production that vanishes into thin air when the electrical system goes off-line for an extended period while repairs are being made. Avoiding the cost of one accidental injury can be used to cost-justify a more robust safety programs. In any case, the plant’s wiring network needs to be maintained, and the market offers many products that can help make the work easier. It will be worth your time to investigate these and the many other products and services that can keep your plant operating at its peak efficiency.
