Question

8- A 20 KVA, 440/220 single-phase transformer has winding resistance as 0.090 and

Answer 1

The total resistance referred to the HV side will be 0.36 ohm.

What is resistance?

Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.

The total resistance referred to HV side is;

$\rm \frac{R_H}{R_L} =(\frac{V_P}{V_S})^2 \\\\ R_H=R_L(\frac{V_P}{V_S})^2\\\\ R_H=0.090 \times (\frac{440}{220})^2\\\\ R_H=4 \times 0.090 \\\\ R_H= 0.36 \ ohm$

Hence, the total resistance referred to the HV side will be 0.36 ohm.
