What is the Transformer of Efficiency?Transformer Efficiency DefinitionTransformer efficiency is the ratio of its output power to input power, usually between 95% and 99%.Factors Affecting EfficiencyEfficiency depends on copper losses, iron losses, dielectric losses, and stray load losses.Efficiency CalculationEfficiency is calculated using OC and SC tests, which measure core and winding losses.Maximum Efficiency ConditionsMaximum efficiency is achieved when copper losses equal core losses, typi
