Arrester Forensic Principles

This month’s Featured Technical Paper is from the Proceedings of the 2018 International Conference of Doble Clients. The paper is titled: Arrester Forensic Principles.



The purpose of this paper is to give guidance on the subject of arrester forensics to the engineer or technician tasked with finding out why an arrester failed. Forensics in this case means the evaluation of an arrester or arrester components to determine the reason why it or its companion arrester has become inoperative. Arresters are a surge diverter for lightning and switching surges that can at times can be overloaded resulting in their end of use. This paper will give guidance on how to test and search for the root cause of the arrester’s terminal overload.
