Voltage regulation measures the change in secondary terminal voltage from no-load to full-load: $$ VR = \fracV_s,nl - V_s,flV_s,fl \times 100% $$ m%C3%A1quinas el%C3%A9ctricas chapman 4ta pdf
An ideal transformer assumes no losses and perfect magnetic coupling. The relationship between voltage and turns is defined by: $$ \fracV_pV_s = \fracN_pN_s = a $$ Where $a$ is the turns ratio. : Basic principles of DC commutation
