Predictive Maintenance with Travelling Wave Fault Location
The need to detect the fault location in a transmission line as quickly and accurately as possible has increasingly been considered by companies in the electric power sector.Market deregulation has changed the way transmission utilities manage their lines,as they are not paid by the amount of power transmitted,but rather by the availability of their lines.Thus,fault location systems that can reach higher accuracy to estimate the fault location minimize the downtime of the line and,therefore,the application of penalties.Impedance-based fault location methods usually are not efficient in high impedance events.Traveling wave-based fault location technology provides good estimation independently of the type of the fault.This paper explores the application of TWFL in several transmission lines of various Brazilian utilities and the results obtained in the field.The changes in maintenance routine derived from these projects,as well as the systems implemented,are described and discussed in the results of the paper.
