OVERVIEW OF THE LIGHTNING-INDUCED OUTAGE RATE ESTIMATOR

This month’s Featured Technical Paper is from the Proceedings of the 2021 International Conference of Doble Clients. The paper is titled: Failure Root Cause Analysis on a 280MW Turbo-generator 2-Pole Rotor: Overview of the Lightning-Induced Outage Rate Estimator.

Abstract

This paper is an overview of an open-source software tool that can be used to determine the direct strike outage rate of a distribution or transmission line. The fundamentals of the software package is reviewed and explained. Two quick studies of a line are completed to show how the tool can be used. In the first study, arresters are installed at different locations on the line. The results show that arresters do not always make a difference if not installed in the correct locations. A second study is done to show the effect of changing tower grounding resistance. The results of this study show the limited effect an improvement in ground resistance can have on a system.
