   How do you calculate the efficiency of a transformer?

   • The efficiency (η) of a transformer is defined as the ratio of output power (Po) to the input power (Pi) and is expressed as a percentage: η = (OutputPower / InputPower) × 100 In terms of volt-amperes (VA), the efficiency of a transformer can be calculated as: η = ( OutputVA × cos ϕ) ( InputVA) × 100 Where, Cosφ is the power factor of the load.
