Convolutional Neural Network and Transfer Learning for High Impedance Fault Detection

Abstract

This letter presents a novel high impedance fault (HIF) detection approach using a convolutional neural network (CNN). Compared to traditional artificial neural networks, a CNN offers translation invariance and it can accurately detect HIFs in spite of variance and noise in the input data. A transfer learning method is used to address the common challenge of a system with little training data. Extensive studies have demonstrated the accuracy and effectiveness of using a CNNbased approach for HIF detection.
