If you assess the cost of power interruptions, you’ll soon find out that every second of power outage could be incredibly costly in terms of lost business. If you add penalties and service costs, you’ll agree that it’s much more convenient to plan a better quality electrical installation. Selectivity is a known key factor for preventing general outages.
Better power quality through selectivity also prevents voltage instability and network disturbances. These phenomena damage the DC power supplies of computers, shorten the life of electronic equipment and can lead to loss of data.
If you’re dealing with industrial processes, a good quality energy flow maintains stability in rotating machines. A properly energized machine lasts longer and performs better, thus saving money.
