The main subject of this paper is the sensing of network anomalies that span from harmless
impedance changes at some network termination to more or less pronounced electrical …

The aim of this paper is to provide the theoretical fundamentals needed to monitor power
grids using high-frequency sensors. In our context, network monitoring refers to the …

A major aspect in power line distribution networks is the constant monitoring of the network
properties. With the advent of the smart grid concept, distributed monitoring has started …

Occurrence of high impedance faults (HIFs) in rural overhead power distribution networks
may cause safety and economic issues for both public and the utility. Such faults may not be …

An on-line method for detecting and locating a faulty node in the utility grid is proposed for
smart grids. The method is based on injection of high frequency (A-Band) current signal into …

Monitoring and control of network constituents are integral aspects of the smart grid. In this
paper, we present a technique for monitoring one such network asset, the underground …

This paper presents a transient-based algorithm for high-impedance fault identification on
distribution networks. It uses the discrete wavelet transform to monitor high-and low …

An effective power system protection scheme has to be able to detect and locate all
occurring faults corresponding to low and high impedance values. The latter category poses …

This paper presents a novel application of smart meters (SMs) in the high impedance fault
(HIF) detection in distribution systems. Detection of HIF on distribution systems poses a …

This paper proposes an efficient channel impulse response (CIR)-based technique to detect
topology changes in the power grid. The features of the proposed approach include the …
