          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.<br />\n
          \t\t\t\t<br />\n
          This document describes a recommended procedure for measuring insulation resistance of armature and field windings in rotating machines rated 750 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.<br />\n
          The purpose of this recommended practice is to address the following:<br />\n
          a) Define insulation resistance and polarization index testing of the winding of a rotating machine.<br />\n
          b) Review the factors that affect or change insulation resistance characteristics.<br />\n
          c) Recommend uniform test conditions.<br />\n
          d) Recommend information methods for measuring insulation resistance with precautions to avoid erroneous results.<br />\n
          e) Provide a basis for interpreting insulation resistance test results to estimate winding suitability for service or for an overvoltage test. In particular, this standard describes typical insulation problems detected by the insulation resistance test.<br />\n
          f) Present recommended minimum acceptable insulation resistance values and polarization indices for various types of rotating machines.

          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.<br />\n
          \t\t\t\t<br />\n
          This document describes a recommended procedure for measuring insulation resistance of armature and field windings in rotating machines rated 750 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.<br />\n
          The purpose of this recommended practice is to address the following:<br />\n
          a) Define insulation resistance and polarization index testing of the winding of a rotating machine.<br />\n
          b) Review the factors that affect or change insulation resistance characteristics.<br />\n
          c) Recommend uniform test conditions.<br />\n
          d) Recommend information methods for measuring insulation resistance with precautions to avoid erroneous results.<br />\n
          e) Provide a basis for interpreting insulation resistance test results to estimate winding suitability for service or for an overvoltage test. In particular, this standard describes typical insulation problems detected by the insulation resistance test.<br />\n
          f) Present recommended minimum acceptable insulation resistance values and polarization indices for various types of rotating machines.

          Revision Standard - Superseded.<br />\n
          This document describes the recommended procedure for measuring insulation resis-tance of armature and field windings in rotating machines rated 1 hp, 750 W or greater. It applies to synchronous machines, induction machines, dc machines, and synchronous condensers. Con-tained within this document is the general theory of insulation resistance (IR) and polarization index (P.I.), as well as factors affecting the results, test procedures, methods of interpretation, test limita-tions, and recommended minimum values.<br />\n

          This document describes a recommended procedure for measuring insulation resistance of armature and field windings in rotating machines rated 1 hp, 750 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.<br />\n
          The purpose of this recommended practice is to<br />\n
          a) Define insulation resistance and polarization index testing of the winding of a rotating machine.<br />\n
          b) Review the factors that affect or change insulation resistance characteristics.<br />\n
          c) Recommend uniform test conditions.<br />\n
          d) Recommend uniform methods for measuring insulation resistance with precautions to avoid<br />\n
          erroneous results.<br />\n
          e) Provide a basis for interpreting insulation resistance test results to estimate winding suitability for service or for an overvoltage test. In particular, this standard describes typical insulation problems detected by the insulation resistance test.<br />\n
          f) Present recommended minimum acceptable insulation resistance values and polarization indices for<br />\n
          various types of rotating machines.

          This document describes a recommended procedure for measuring insulation resistance of armature and field windings in rotating machines rated 1 hp, 750 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.

          Superseded by 43-2000. Insulation resistance characteristics of rotating-machine windings and the manner in which these characteristics may serve to indicate the condition of the winding are described. The recommended procedure for the measurement of insulation resistance of windings of rotating machines rated 1 hp, 1 kW or greater is presented. The recommended minimum value of insulation resistance of alternating-current and direct-current rotating-machine windings is given. Synchronous machines, induction machines, direct-current machines, and synchronous converters are covered, as well as armature windings and field windings. Fractional-horsepower machines are not included.<br />\n

          The purpose of this publication is to:1) Describe and define insulation resistance as applied to the winding of a rotating machine; 2) Review the factors which affect or change insulation resistance characteristics and recommend uniform test conditions; 3) Outline and recommend uniform methods for measuring insulation resistance together with precautions for avoiding erroneous results; 4) Provide a basis for interpreting insulation resistance test results to estimate the suitability of the winding for service or for overpotential test.; 5) Present equations, based on machine ratings, for the calculation of recommended minimum insulation resistance values for various types of rotating machines.
