IEEE 43-2013 PDF

This was done to accommodate the many changes and observations in insulation chemistry and combinations over the past decades. There were some contentious issues, such as the continued inclusion of random wound machines for specific tests, since the makeup of the working group was focused around large, high voltage machinery with a relatively small contingent of representatives with integral horsepower, random wound machine experience. The result was a document written from the ground up and the inclusion of tests that have been in use for about a century, but not previously included in the standard. The original version of Annex D provided details, including interpretation of the data, which was generally agreed to by the participants with experience performing these tests. However, due to a lack of experience by a significant number of the group related to this test and deadlines for the standard, it was determined that a simple paragraph referencing the testing methodology would be in order.

Full Description Scope This document describes a recommended procedure for measuring insulation resistance of armature and field windings in rotating machines rated W or greater. It applies to synchronous machines, induction machines, dc machines, and synchronous condensers.

It does not apply to fractional-horsepower machines. The document also describes typical insulation resistance characteristics of rotating machine windings and how these characteristics indicate winding condition. It recommends minimum acceptable values of insulation resistance for ac and dc rotating machine windings.

Othere IEEE standards that include information on insulation resistance measurement are listed in Clause 2. The purpose of this recommended practice is to address the following: a Define insulation resistance and polarization index testing of the winding of a rotating machine.

In particular, this standard describes typical insulation problems detected by the insulation resistance test. Revision Standard - Active. The dc voltage tests procedures for the measurement of the insulation resistance and polarization index of insulated stator, and rotor windings and how to interpret the results are described in this recommended practice.
