To calculate transformer ohmic loss, you can use the Transformer Copper Loss Calculator

The term “copper loss” refers to the heat generated by electrical current in any electrical device. This loss can be calculated using Joule’s first law, which states that the energy lost per second increases as the square of the current flowing through the winding, where a and c are the current and b and d are the resistance. To calculate transformer ohmic loss, you can use the Transformer Copper Loss Calculator provided below. Simply input the necessary values to obtain the results for your calculation.

    l = (a2 × b) + (c2 × d)

    where,

    • l = Copper Loss
    • a = Primary Winding Current
    • b = Primary Winding Ohmic Resistance
    • c = Secondary Winding Current
    • d = Secondary Winding Ohmic Resistance
