Test standard

IEEE 43-2024

Standard for testing the insulation resistance of electrical machines

Standard for Testing Insulation Resistance of Electric Machinery

This document describes a method for measuring the insulation resistance of armature- and field windings in rotating machines with a rated power of 750 W or more. It applies to synchronous machines, induction machines, direct-current machines, and synchronous capacitors.


SCHLEICH supplies testing equipment designed to meet this standard at specialized .
These devices are very user-friendly, ideal for practical use, and generate all necessary documents and certificates for you upon completion of the test.
