Given:

  • no-load voltage (E_2) = 240 volts
  • full load voltage (V_2) = 220 volt

To Find:

  • Voltage regulation in percentage of the transformer

Solution:

The voltage regulation of transformer is  the change in secondary terminal voltage (V_2) from no-load to full load at constant primary voltage and temperature.

% Regulation of transformer   = \frac {(E_2 - V_2)}{E_2} \times 100

Putting the value

                               = \frac {(240 - 220)}{240} \times 100

                               = \frac{20}{240} \times 100

                               = 8.33 \%

Thus, % Regulation of transformer  8.33 \%

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%.
