Abstract

Various reflectometry methods to locate power cable fault have been studied. But, most related studies has been verifying by simulation and laboratory test and study in conditions similar with real cable fault filed was not performed due to the absence of cable fault test field. Therefore, this paper design and construct test field for the standardized performance test and the operating education of cable fault location equipments. In the constructed test, open, short, half open and poor contact fault at 100m, 200m location of cable was produced and 1km cable role was installed for maximum distance measurement test. The test field will be used in the development and standardization of cable fault location technology, and te performance evaluation and certificate test of the related equipments.

전력 케이블의 고장에 대한 위치를 검출하기 위한 다양한 반사파 계측법들이 연구되고 있다. 하지만 대부분 관련 연구들이 시뮬레이션과 실험실에서의 성능 검증이 이루어지고 있고, 실제 현장과 비슷한 조건에서의 연구는 실증 시험장의 부재로 인해 이루어지지 못하고 있다. 따라서 본 논문에서는 케이블 고장 검출 장치의 표준화된 성능 시험과, 장비 운영 교육을 위한 실증 시험장을 설계 및 구축하였다. 구축된 실증시험장에서는 100m, 200m 거리에서 단선, 합선, 반단선, 접촉 불량 고장을 발생시켰고 최대 거리 측정 시험을 위해 1km 케이블을 설치하였다. 이러한 실증시험장은 향후 케이블 고장 검출 기술의 개발과 표준화, 그리고 장비 성능 검증 및 인증 시험 등을 위해 활용될 수 있을 것이다.
