Define the percentage voltage regulation and efficiency of a power transformer. |
|
Answer» Voltage regulation is the difference between no load voltage and full load voltage by no load voltage. Voltage regulation = No load voltage – Full load voltage / No load voltage. Voltage regulation is mentioned in % (percentage). % Voltage regulation = No load voltage – Full load voltage * 100 / No load voltage. Efficiency of a transformer is the ratio of output in watts and input in watts. Efficiency = Output in watts / Input in watts. % Efficiency = Output in watts * 100 / Input in watts. % Efficiency = Output in watts * 100 / Output in watts + losses. |
