Transformer Grounding & Cable Concepts Explained

Sharing of Transformer Concepts and Terminology The zero-mode impedance of a load is infinite, and its line-mode impedance is also extremely large, approximately 100 times that of the line-mode impedance of the line. The capacitance to ground of a cable is 25-50 times that of an overhead line. The f
