In-service testing of temporary grounding jumper assemblies using time domain reflectometry

Abstract

The electrical utility industry relies on safety procedures and equipment to protect linepersons from the hazards associated with high voltages. The current standards and test methods for protective jumper assemblies are disjointed and largely implemented in an ad hoc fashion. This thesis reviews the current state of the art and the standards and practices currently in place. Models, analyses and an investigation of testing methods are used to propose a comprehensive test plan and new test fixtures to provide accurate and traceable results. These results will allow the electrical utilities to insure that the protective jumper assemblies are in fact providing the protection needed by their workers.
