Title:
SYSTEM AND METHOD FOR MONITORING AGING STATE OF POWER CABLE
Document Type and Number:
WIPO Patent Application WO/2023/224328
Kind Code:
A1
Abstract:
The present invention relates to a system and method for monitoring the aging state of a power cable, in which a measuring unit measures the elongation at break of at least one power cable, a data generation unit generates a relational expression on the basis of the elongation at break of each of a heated cable, to which voltage has been applied to raise the temperature thereof, and a non-heated cable, to which no voltage has been applied, from among the measured cables, and an aging state derivation unit derives the aging state of a target power cable by calculating the elongation at break of the target power cable, of which the aging state is to be monitored, by using the relational expression. Accordingly, it is possible to verify the aging state of a power cable quickly and efficiently and to improve the credibility of the aging state of the power cable.
