Pollution is the single largest cause of transmission/distribution line outages, next to lightning, which result in expensive power outages. A major significance of the problem is that it can repeatedly occur even at ...

Outdoor insulators are one of the most important parts of a power system. The reliability of a power system depends also on the reliability of the insulators. The main functions of an insulator used for outdoor applications ...

Frequency response analysis (FRA) of transformers is universally accepted as a highly sensitive tool to detect deformations in its windings. This is evident from the fact that customized commercial equipment (popularly ...

The applications of ad hoc wireless networks envisaged in this thesis are those related to issues of disaster management, rehabilitation, security and defense. The circumstances in such situations warrants the deployment ...

This thesis deals with the modelling, simulation and control of Permanent Magnet Synchronous Machines (PMSM) used specially in electric and hybrid vehicles. With the availability of fast semiconductor switches and high ...

Graph cuts have emerged as an important combinatorial optimization tool for many problems in vision. Most of the computer vision problems are discrete labeling problems. For example, in stereopsis, labels represent disparity ...

With limited enhancement or expansion of the transmission infrastructure, the contemporary power systems are operating under more stressed conditions. It becomes important to fully utilize the existing transmission system ...

The overall reliability of a power transformer depends to a great extent on the sound operation of the bushings thereof. In view of its overwhelming advantages, resin impregnated paper (RIP) is acquiring prominence over ...

A split-phase induction motor (SPIM) is obtained by splitting each of the three-phase stator windings of an induction motor into two equal halves. This results in two sets of three-phase windings with a spatial angle ...

The modern day power system is witnessing a tremendous change. There has been a rapid rise in the distributed generation, along with this the deregulation has resulted in a more complex system. The power demand is on a ...
