Problems solved by technology

[0002] Most of the power cable degradation detection uses a part of anti-electricity detection, but this has the problem that it is difficult to provide high reliability when diagnosing defects in the main insulation layer of the cable
[0003] According to the conventional technology, the pulse propagation characteristic analysis method has been tried, but there is a problem that it is difficult to obtain information related to the specific progress state of the defect, such as the size and penetration depth of the defect that occurs in the cable.

Abstract

The invention relates to a power cable deterioration detection device and a method thereof. The power cable degradation detection device includes a memory storing a power cable degradation detection program and a processor executing the program. The processor configures a diagnostic pulse train including a plurality of short pulses of different sizes and widths and performs pulse propagation characteristic analysis.

Description

technical field [0001] The invention relates to a power cable degradation detection device and a method thereof. Background technique [0002] Most of the power cable degradation detection uses a part of anti-electricity detection, but this has the problem that it is difficult to provide high reliability when diagnosing defects on the main insulation layer of the cable. [0003] According to the prior art, a pulse propagation characteristic analysis method has been tried, but there is a problem that it is difficult to obtain information on the specific progress state of the defect, such as the size and penetration depth of the defect occurring in the cable. Contents of the invention [0004] The problem to be solved by the invention [0005] The present invention is proposed to solve the above-mentioned problems. The purpose of the present invention is to provide a power cable degradation detection device and method that can obtain specific progress status information rel...
