Calculate the voltage regulation in percentage of the transformer if the no load voltage is 240 volt and full load voltage is 220 volt?
Answers
Answer:
Given:
no-load voltage (E_2) = 240 volts(E

)=240volts
full load voltage (V_2) = 220 volt(V
2
)=220volt
To Find:
Voltage regulation in percentage of the transformer
Solution:
The voltage regulation of transformer is the change in secondary terminal voltage (V_2)(V

) from no-load to full load at constant primary voltage and temperature.
% Regulation of transformer = \frac {(E_2 - V_2)}{E_2} \times 100=

Answer:
No voltage = 240 Volts
Full load voltage = 220 Volts
To find: Voltage regulation in percentage
Solution:
The formula for voltage regulation in percentage is given by:
% Voltage regulation = V no load - V rated load / V rated load x 100
% Voltage regulation = 240 - 220 / 220 x 100
% Voltage regulation = 20 / 220 x 100
% Voltage regulation = 0.090 x 100
% Voltage regulation = 9 %
Thus the percentage of voltage regulation is 9%.
