This paper presents how interpretation of Sweep Frequency Response Analysis (SFRA) traces can be done for the open circuit and short circuit winding faults on the 10kVA power transformer. The power transformer of rating 10kVA, 11,000V/440V, 3-phase, 50Hz, Dyn11 has been specially developed in-house for carrying out SFRA testing by practically simulated various transformer damages on it. Authors have...
Information technology played an important role in information and knowledge dissemination in the last decade in the almost all the domains through the development of internet, wireless, satellites and mobile based intelligent knowledge based information system. These systems need timely expert advice to make them more productive and competitive. By implementing them as knowledge servers, it becomes...
The paper titled ldquopartial discharge in HV equipmentsrdquo mainly consists of details about partial discharge detection system and analysis of partial discharge distributions. The ever increasing demand for electrical energy has led to erection of high voltage transmission lines of 765 kV, 1000 kV, HV cables, capacitors etc. As the voltage goes high, even if the losses become considerably less,...
