Abstract :
The insulation resistance profile polarization index curve can be a powerful tool to understanding the condition of a ground wall insulation system when properly applied. The purpose of this paper is to review the success of several approaches including: all phases to ground; each phase to ground with other phases grounded; and, time applied. The conclusion will be a series of observations as to the effectiveness of this prognostic method for condition monitoring.
