Question
(b) Mr. Musa Al Biruni is analyzing a 100 kVA, 60 Hz, 7200-48ov, single phase transformer, which
has the following parameters expressed in ohms;
R-3.06, XHS-6.05, Xu=17809, R-0.014, X-0.027, R=71400
The transformer is supplying a distribution side load that draws a rated current at 480V and 75
percent power-factor lagging. Sketch the appropriate equivalent circuit and determine (a) the
equivalent resistance and equivalent reactance referred to high side (b) the input voltage to the
transformer (c) the exciting current and its core loss and magnetizing components
