On Line Detection of Partial Discharge in High Voltage Equipment Using Acoustic Emission Technique

Throughout the decade, generation of the high voltage (HV) electrical power gradually increases due to increase of demand in industrial growth as well as to meet the demand for modern civilization. Extensive electrical power networks installations have been built in industrialized countries and are being constructed in developing countries at a rapid increasing rate. The major function of such power systems is to generate, transport and distribute electrical energy over large geographical areas in an economical manner while ensuring a high degree of reliability and quality of supply. Apart from these, high voltages are also widely used in many industrial as well as engineering applications. In all such applications, the high cost and comparatively long life span of HV power equipments are…
