Fault analysis on electrical distribution system

This paper summarizes the activities conducted at Progress Energy Carolinas (PEC) to investigate electrical faults that occur on the electric distribution system. PEC has developed a series of web tools that are used to analyze data collected by the Feeder Monitoring System (FMS), the Outage Management System (OMS), and Distribution Supervisory Control and Data Acquisition (DSCADA) System. These tools were developed to assist engineers and operations personnel in locating faults and identifying causes of both permanent as well as temporary faults.
