| Abstract |
This paper studies a highly reliable preventive diagnosis method through insulation diagnosis of power facilities. First, the pattern of radiation electromagnetic waves emitted to the outside in the event of partial discharge was confirmed by modeling the structure of the pole transformer. Second, a sensor to measure radiated electromagnetic waves generated when a pole transformer malfunctions was designed, manufactured, and its characteristics were confirmed. The applicability of sensors for fault diagnosis of power facilities for distribution was confirmed through design and experiments. As a result, the frequency band can be used as an insulation diagnostic sensor because it is measured through experiments that the reflection loss satisfies -10dB at 1.5 to 7GHz. It is thought that the fault diagnosis sensor presented in this paper can be used as a sensor by preventing and diagnosing distribution-grade power facilities in the future. |
