Calculate the voltage regulation in percentage of the transformer if the no load voltage is 240 volt and full load voltage is 220 volt? Do it with formula.
Answers
Given:
- no-load voltage
- full load voltage
To Find:
- Voltage regulation in percentage of the transformer
Solution:
The voltage regulation of transformer is the change in secondary terminal voltage from no-load to full load at constant primary voltage and temperature.
% Regulation of transformer
Putting the value
Thus, % Regulation of transformer
Thus the percentage of voltage regulation is 9%.
Explanation:
We are given that:
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%.
