Use a diversity factor of 1.5. Solution. Calculate demand for each feeder: • 400 kVA × 95% = 380 kVA
WebPower factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA). Apparent power, also known as demand, is the measure of the amount of power used to run machinery and equipment during a certain period. It is found by multiplying (kVA = V x A). The result is expressed as kVA units. WebA KVA is 1000 volt-ampere. A volt is an electrical pressure, and an ampere is an electrical current. Here, the apparent power is equal to the product of the volts and amperes. A watt …
