Abstract

A diagnostic/prognostics system for failure detection in an electrical insulation system is provided. The system includes at least two current transformers designed to detect high frequency component signals from the insulation system. The system also includes a data acquisition module coupled to the at least two current transformers, wherein the data acquisition module receives the high frequency component signals and analyzes the received high frequency component signals to identify one or more faulty components in the electrical insulation system.
