Short Circuit Analysis

X/R Ratio

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

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…
