What is the relationship between efficiency and the power ,

Apr 27, 2018· A good question! One way of writing the equation for efficiency is: Efficiency = (Output power) / (Output power + losses) For a transformer running at full rated VA, the losses will be constant no matter what the load power factor However the (tr....

Simple description of Power Factor Correction

For example, a large electric motor will typically have a Power Factor of about 085 at full load If we have a hypothetical electric motor rated at 100kW, then ignoring the inherent inefficiency of the motor, when running at full load the electricity supplier would have to supply 100÷085=118kVA to provide the 100kW to run the motor...
