Electromagnetic Time Reversal for on-line Partial Discharge Location in Transmission and Distribution Networks

OVERVIEW
Energy is crucial for the developing World and must be provided when needed to avoid serious impact on society.
Among all energy forms, electricity has an increasingly central role.
Electricity security is the power system’s capability to withstand disturbances or contingencies with an acceptable service disruption and represents a crucial concern for policy decision making at all levels.
Usually, service disruption is due to cables insulation damage, often caused by, or accompanied by, a partial discharge (PD) event that is a localized electrical discharge that partially bridges the insulation between conductors.
Since PD is one of the best early-warning indicators of insulation damage, the on-line PD location is the most suitable method of monitoring network integrity and a desirable network protection method to guarantee electricity security.
The project’s main objective is to develop a new method for on-line PD location based on the innovative electromagnetic time reversal (EMTR) theory.
