Analysis of a cable lug failure for a recycle compressor trip

Abstract

This article presents an analysis of an electrical contact terminal lug failure on medium voltage system. The analysis considers different aspects of the electrical contacts, such as: contact resistance, contact force, stress, motion, lubrication. The case study refers to a cable lug failure on a compressor supply. Different situations are to be considered to find the cause of the default. Conclusion and proposed actions are finally presented.
