DEVICE FOR SPACE CHARGE MEASUREMENT CORRESPONDING TO CABLE INSULATION THICKNESS PARAMETER AND SPACE CHARGE MEASUREMENT METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2024/096224
Kind Code:
A1
Abstract:
The present invention relates to a space charge measurement device for measuring a space charge distribution in a cable by a pulsed electro-acoustic (PEA) method and a space charge measurement method using same, wherein, for cables having various insulation thicknesses, the thicknesses of a piezoelectric element and an absorber of a module sensor can be changed so that it is possible to accurately and easily measure a space charge distribution in a cable.
