چکیده
Abstract Mechanical shift of windings is serious problem power transformers which belong to the very significant components engineering system. displacements and following insulation failure due short circuit inrush currents can lead an emergency situation. That’s why effective control technology relevant task a current engineering. A new approach winding state described in paper. The based on nanosecond probing impulse duration with (no more than 20 ns) rapidness front impulse. experimental results sensitivity growth at decreasing pulse are shown. equipment research described. It established that has optimum value around 100ns. shown it possible do condition under operating voltage. both shorter probe allows upgrading common effectiveness diagnostic technology.

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولComparison of Impulse Wave and Sweep Frequency Response Analysis Methods for Diagnosis of Transformer Winding Faults
Monitoring of winding faults is the most important item used to determine the maintenance status of a transformer. Commonly used methods for winding-fault diagnosis require the transformer to exit operation before testing and an external exciting signal, whether the transformer is malfunctioning or not. However, if an overvoltage signal can be regarded as a broadband excitation source for fault...
متن کاملCharacterization of Power Transformer Electromagnetic Forces Affected by Winding Faults
Electromagnetic forces in power transformer windings are produced by interaction between the leakage fluxes and current passing them. Since the leakage flux distribution along the windings height is in two axial and radial directions, so the electromagnetic forces have two components, radial and axial. There is a risk that a large electromagnetic force due to the short circuit or inrush current...
متن کاملTransformer Models for Detection of Incipient Internal Winding Faults
A method of modeling internal turn-to-earth and turn-toturn faults in distribution transformer is discussed in this paper. The models are entirely compatible with the Alternative Transients Program(ATP). The simulation of the faults is based on known leakage factors between the various coils of the transformer. These leakage factors are evaluated by using a simple method implemented in this pap...
متن کاملA High Frequency Transformer Winding Model for FRA Applications
Frequency response analysis (FRA) is a method which is used to detect mechanical faults in transformers. The FRA response of a transformer is determined by its geometry and material properties, and it can be considered as the transformer’s fingerprint. If there are any mechanical changes in the transformer, for example if the windings are moved or distorted, its fingerprint will also be changed...
