Practical diagnostic technique for catenary surge arrester in electric railway

전차선로용 피뢰기 진단기법 적용 연구

This paper describes the measurement result of leakage current flowing arrestors connected in catenary line to propose an optimal management methods. 27 arrestors set in 7 locations were tested. The leakage currents are included a harmonics of electric train during the operation of electric train in feeding section and in case of feeding earthing system.
