Title:	TRANSFORMER PROTECTION.
Authors:	Stringer, N. T.¹
Source:	Encyclopedia of Electrical & Electronics Engineering. 1999 1st Edition, Vol. 22, p348-359. 12p.
Subjects:	Electric transformers, Electric power, Voltage regulators, Electric currents, Electronics, Electric machinery
Abstract:	The article reports that a large number of transformers are typically installed in any given power system. This represents a large investment for both utility and industrial power systems. These devices provide the necessary voltage conversions to transport power through the system. Faults within a transformer can cause a tremendous amount of damage in a very short time. Magnetizing inrush is a transient current that results from the sudden change in exciting voltage across a transformer's windings. Most transformers are equipped with either a high-voltage or low-voltage tap changer.
