INTRODUCTION
* Use of air gap magnetic flux probes-proven effective in detection of generator winding shorted turns
* Improve quality of predictive maintenance decision when or if to perform rework
* Can pinpoint the no: & location(pole & coil) of shorted turns without having to take generator offline
EFFECTS OF SHORTED TURNS IN ROTOR WINDINGS
* If percentage of total turns shorted out is small, the generator may be able to run at rated load for years without further proble ....etc

Chapter 1
INTRODUCTION
Twelve to fifteen percentages of transformer failures are caused by winding deformations provoked by the high electrodynamics forces appearing during short circuits. These geometric vibrations lead to an increase of the winding vibration and, consequently, to an increase of the solid insulation mechanical fatigue. In this way, the isolation can be degraded and short circuit between turns will appear. On the other hand the change in the distance among the conductor implies a change in the serie ....etc

Transformer Basics
An electrical device that transfers energy from one circuit to another purely by magnetic inductive coupling.

Review of transformer losses
No load Loss (Excitation Loss) includes the hysteresis loss and eddy current loss.
excitation loss: energy lost by reversing the magnetic field in the core by the alternating AC.
mechanical loss: bearing friction,brush friction and windage loss

Load Loss (Impedance Loss)
Stray loss: It includes distortion of air-gap flux and also due to the due to non uniform ....etc

ABSTRACT

This paper describes in detail, field experiments performed on a single-phase, distribution transformer to study the behavior of transformer terminal parameters during internal winding faults. A custom-built transformer provided with external taps was used for these tests. The taps were used to stage various internal winding faults in the transformer. Terminal values of voltages and currents were monitored and the results presented. A comparison of these results with simulation results is also presented
