This standard applies to ac high-voltage circuit breakers with rated maximum voltage above 1000 V. It defines various tests that are made on ac high-voltage circuit breakers, except for generator circuit breakers, which are covered in IEC/IEEE 62271-37-013:2015 (formerly IEEE Std C37.013(TM)-1997). It specifies the tests and describes the accepted methods used to verify assigned ratings defined in IEEE Std C37.04(TM). It also describes the test procedures associated with production and field installation. The test procedures are divided into the following classifications: a) Design tests; b) Production tests; c) Conformance tests; d) Field tests. NOTE--Design tests are referred to as “Type” tests, and Production tests are referred to as “Routine” tests in IEC standards.

This recommended practice outlines a test procedure for comparing expected life, at rated temperature, of two or more sealed insulation systems. The procedure is limited to insulation systems for ac electric machines using random-would stator coils. It is the intent of this procedure to evaluate insulation systems for use with air cooling under severe environmental conditions where the insulation is exposed to conducting contaminants. It does not cover special requirements such as those for… read more machines enclosed in gas atmospheres, subjected to strong chemicals, or to submersion in liquids. The procedure includes instructions for the following: (b)Testing candidate systems in comparison with known systems having a proven record of service experience (b)Interpretation of the results read less

This guide describes three methods used in the measurement of the power factor of inductive low-voltage (1000 V and lower) test circuits. These methods may be used at any frequency; however, the values in the tables are specifically for 60-Hz test circuits. These methods are as follows: a) Ratio method; b) DC decrement method; c) Phase relationship method. Table 1 lists the preferred methods to be used for different levels of test currents and for different levels of power factor. While this… read more guide is primarily intended for use on low-voltage test circuits, the methods discussed are also usable at higher voltages. read less

This standard covers the application guide for transient recovery voltage requirements for ac high-voltage circuit breakers rated above 1000 volts and on a symmetrical current basis. The capability limits of these circuit breaker interrupting devices are determined largely by the transient recovery voltages. The guide for application is not included in other existing circuit breaker standards.

This document describes very low frequency (VLF) testing of ac electric machines. It covers acceptance testing of new machines in the factory or on-site after erection. Also covered is the routine maintenance testing of machines that have been in service. In order to facilitate communication and comparison among investigators, this document recommends that the VLF used be 0.1 Hz ±10%. For ac electric machines, voltages between 3.3 kV to 30 kV are considered to be high voltage machines.

This recommended practice outlines a test procedure for the evaluation of the impulse voltage capability of insulation systems of form-wound alternating current rotating electrical machinery. This test procedure forms a base for the accumulation, analysis, and reporting of information concerning impulse voltage withstand strength of ground and turn insulation, both new and aged. The immediate goal is a better understanding of relevant aging mechanisms; the ultimate aim of this document is to… read more aid in estimating life of an insulation system under speciÞed service conditions. It must be emphasized that this test procedure is intended, at this time, for trial use. Future revisions, made after experience with it, should result in more deÞnitive speciÞcations being possible. This procedure recommends the use of multi-factor aging tests, combining thermal and electrical aging in order to address the withstand capability of micaceous insulation. Variations of this procedure may be tried, such as for voltage ratings other than 6.9 kV and 13.8 kV, for turn insulations other than mica, and for various impulse wave forms. The procedure is primarily directed toward providing a qualification test for the turn insulation in regard to its ability to withstand impulses that might be impressed on the terminals of a machine and that result from switching surges, lightning, or other disturbances. It will also provide information on the ability of the ground insulation to withstand impulses. In addition, the test model used in the tests described herein will be suitable for testing the strand insulation, if that is desired, although it is not a function of this qualiÞcation test procedure. read less
