Executive Summary : | Power Apparatus are substantial and key elements of electrical energy networks. The power Apparatus will be insulated to distribute reliable and safeguarded service in the power systems. Owing to uninterrupted operation of power apparatus abrupt failure and disruptions takes place as the insulation degrades with time. Thus continuous quality of the power apparatus insulation monitoring is essential and widely accepted evaluation for PD's identification. PD monitoring techniques can be performed either online or offline. These online monitoring techniques do not interrupt its normal operation whereas offline monitoring techniques require disconnection from the power supply.
PD is a quite cumbersome incident and random in nature. There are still distinct challenging aspects like accurate evaluating PD measurements, analysing the captured PD signals relevantly and thereafter preparing a report on insulating system of the condition assessment. The present work is focused on design of a non-invasive monitoring type of sensor technique for PD detection and source localization in power apparatus using distinct algorithms.
In this project, robust algorithms have been investigated for localization of PD source in power apparatus using non-invasive monitoring techniques. These approaches are applied to laboratory as well as field PD measurements of case studies. These case studies demonstrate merits of the proposed algorithms when compared to conventional techniques in the PD source localization. |
