    Transformer Heat Release given kVA, Z% and X/R

    Transformer kVA, Z% and X/R are commonly available. Proposing the following equation for transformer heat release: kW = kVA * Z% / SQRT((X/R)2 + 1) Is this equation legitimate? Equation givens: Q = X/R and thus X = Q * R Z2 = X2 + R2 Combining given equations to eliminate X: Z2 = (Q * R)2 +...
