The main function of an Electrical Power Distribution system is to provide power to individual consumer premises. Distribution of electric power to different consumers is done with much low voltage level. Distribution of electric power is done by distribution networks. Distribution networks consist of following main parts

1. Distribution substation
2. Primary distribution feeder
3. Distribution Transformer
4. Distributors
5. Service mains

Little attention or thought is given to these critical assets until a failure occurs. With a little thought and planning for maintenance, most electrical system failures can be eliminated.

You've probably heard the athlete's proverb, "No pain, no gain." In the electrical world, it's "No maintenance, no operations." How much maintenance do you need?

Your power distribution system is your backbone. Unfortunately, many organizations operate on the "if it ain't broke, don't fix it" principle. Thus, many companies underfund (and undermine) their maintenance departments. As a result, maintenance groups routinely make emergency repairs at excessive cost. You may have been in such a situation. And you may have said, "Now they'll listen to us. Now we'll do the maintenance we need to do."

Will your company ensure timely completion of maintenance and repairs for more than an hour after the crisis has passed? Unfortunately, the answer is usually no. The predictable result is more unplanned downtime.

What about those organizations with comprehensive preventative/predictive maintenance programs? Every electrical and mechanical device undergoes scheduled inspections and maintenance. Skilled maintenance people identify and repair potential equipment problems before they become major events. This approach actually builds the bottom line. Feel fortunate if your company prescribes to this maintenance style.
