Abstract

This paper introduces some field analyses of the wooden pole fire reports and online condition monitoring recorded data for line insulators of 33kV and 132kV overhead power lines of Petroleum Development Oman (PDO). From the statistical analysis of PDO pole fire reports, it was found that PDO southern directorates had higher number of pole fires during May-September 2004. Pole fires mostly occur for single poles of 33kV distribution lines close to graded roads, where the most common burning locations are at crossarm fixation and at ground foundation. Pollution monitoring systems provide very useful information which can be used to predict the pole fire events.
