Background of X/R Short circuit calculations are actually just an elaborate version of Ohm’s Law. One of the key components in the calculation process is to determine the total impedance of the circuit from the utility/source, through the transmission system,…
How to Perform a Power Factor Study – kVA Demand Rate: Jim Phillips, P.E. A power factor study is a key to properly determining a system’s power factor correction requirements. A study determines capacitor size and location as well as the number of steps and incremental sizes to be switched. A…
Those responsible for a facility’s operation hear the same thing over and over again – reduce costs and improve productivity. Much attention has been given to reducing raw material and labor costs, increasing production efficiency, automating processes, and other key areas, but what about the often overlooked cost of an electrical outage? Depending on the type of facility, one outage can paralyze building systems and cost thousands – or even millions – of dollars in lost production, downtime, damage to
