Go back to Menu↑ Watts to kVA calculation formula: Power Factor is the ratio of true power to apparent power. Power Factor is the cosine of the phase angle between current and voltage. A high power factor signals efficient utilization of electrical power, while a low power factor indicates poor utilization of electrical power. as tansformers and motors having power factor less than 1.0 are generally rated in KVA.į.p: Power factor is the ratio of working power to apparent power. It measures how effectively electrical power is being used. KVA is larger than KW because loads are inductive such as motors, discharge lighting, reactors and more current is required to keep the magnetic field energized than is -turned into heat (KW). KVA: A kilovolt-ampere, commonly referred to as a kVA, is commonly used as a unit of power in obtaining the electrical capacity of circuit breakers, uninterrupted power supplies and wirings. Resistive devices or loads such as heaters, incandescent lamps are rated in Watts. One watt is one joule (energy) per second (1 W = 1 J/s). Power in watts is the rate at which energy is consumed (or generated). The real power in watts is the power that performs work or generates heat. It is the power that actually powers the equipment and performs useful work. Watts: is Working Power (also called Actual Power or Active Power or Real Power).
