It applies to synchronous machines, induction machines, dc machines, and synchronous condensers. Contained within this documentþis the general theory of insulation resistance (IR) and polarization index (P.I.), as well as factors affectingþthe results,þtest procedures, methods of interpretation, test limitations, and recommended minimum values.
