Abstract

This work applies the probabilistic failure risk evaluation of metal-oxide (MO) arresters in order to assess the performance of double arrester lightning protection configuration in lightning protection of pole-mounted transformers (PMTs). Therefore, an 11 kV distribution line is built-up and simulated in the EMTP-RV software package. Two study-cases of lightning protection analysis are observed: a PMT with single and a PMT with double arrester configuration. Simulation results show that the use of double arrester protection approach reduces failure risk of arresters by 47.86% for an exposure to lightning amplitude of 20 kA, and the annual outage rate of MO arresters shows reduction from 16.99 to 11.4, thus improving the average life expectancy of these protection units and consequently reducing the probability of PMT failure.
