位置標定における重畳最適化法を用いた部分放電源空間標定

抄録

A partial discharge (PD) inside a power apparatus is a symptom of an insulation breakdown and machine trouble and the electromagnetic signals emitted from it interferes with a communication system as a noise. From above, detection and location PD are very important. The method of location PD based on several time delays of arrival of electromagnetic wave emitted from PD among antennas is well known. However, it is difficult to locate PD as a one point. It is better to locate as a space, but as a point. In this paper we propose “Superimposed Positioning Optimization on the Time delay of arrival(SPOT)”as a new method to locate PD. We discuss an effectiveness of “SPOT” and properties of the spaces located.
