Abstract

In the last decades, multiple methodologies and dedicated devices have been developed to assist in locating faults, especially High-Impedance Faults (HIF). However, if the broken cable remains hanging during an HIF, there is no fault current, impeding the current-based HIF location methodologies in detecting the defect. Locating HIFs is crucial for power distribution utilities, not only for improvement of quality service indices, but also for preventing safety issues posed by energized downed power cables. This research deals with a key Smart Grids' component: Advanced Metering Infrastructure (AMI), through Smart Meters' (SM) capability of emitting Last Gasp (LG) alarms, which indicate power outage. Since SMs are massively deployed throughout the power distribution concession area, a second benefit is provided: detection and location of fuse-cleared faults, a type of fault that the power utility is normally aware only through customers' complaints. Finally, a Brazilian power distribution network is considered for case studies aimed to demonstrate HIFs and fuse-cleared faults location. They successfully demonstrate the proposed methodology suitability to assist utilities engineers in addressing those types of faults.
