This part of IEC 60034 describes thermal endurance test procedures for classification of insulation systems used in a.c. or d.c. rotating electrical machines with indirect cooling and form-wound windings. The test performance of a candidate insulation system is compared to the test performance of a reference insulation system with proven service experience. The test procedures described in IEC 60034-18-31 are intended to compare the thermal endurance performance of the mainwall insulation between conductor(s) and ground and,where required by the design of the coil or bar, the insulation between the turns. The test is not intended to simulate the in-service mechanical stresses experienced by the endwinding bracing or support materials. It does not include the evaluation of thermomechanical deterioration by expansion and contraction of insulation during temperature cycling. IEC 60034-18-1 describes general testing principles applicable to thermal endurance testing of insulation systems used in rotating electrical machines. The principles of IEC 60034-18-1 are followed unless otherwise stated in IEC60034-18-31. The thermal class for the insulation system refers to its maximum allowed (“hot spot”) temperature. The average temperature measured in service should not exceed the allowed temperature rise according to IEC 60034-1. NOTE 1 Large machines, especially synchronous generators using bars, may require special thermal evaluation test procedures which are not included in this part. NOTE 2 Recommended parameters for the diagnostic test may be applied according to IEC 60034-18-42 to formwound coils designed with Type II insulation systems for use in converter applications.

This part of IEC 60034 describes the performance characteristics of a.c. electrical machines for use on converter supplies. For electrical machines specifically designed for converter duty application design features are defined. It also specifies the interface parameters and interactions between the electrical machine and the converter including installation guidance as part of a power drive system, but except for the voltage at the power interface which is described in IEC 61800-8. The general requirements of relevant parts of the IEC 60034 series of standards also apply to electrical machines within the scope of this technical specification. For electrical machines operating in potentially explosive atmospheres, additional requirements as described in the IEC 60079 series or IEC 61241 series for dust ignition proof apply. This technical specification is not primarily concerned with safety. However, some of its recommendations may have implications for safety, which should be considered as necessary. Where a converter manufacturer provides specific installation recommendations, they should take precedence over the recommendations of this technical specification.

This part of IEC 60034-18 describes test procedures for the evaluation of electrical endurance of insulation systems for use in a.c. or d.c. rotating electrical machines using form-wound windings. The test procedures are comparative in nature, such that the performance of a candidate insulation system is compared to that of a reference insulation system with proven service experience. The test procedures are principally directed at the insulation systems in air-cooled machines but may also be used for evaluating parts of the insulation systems in hydrogen cooled machines. Note that the qualification procedures of inverter duty insulation systems for form-wound windings can be found in IEC 60034-18-42.

This part of IEC 60034 is applicable to the on-line detection and diagnosis of failures at the active parts of multi-phase rotating electrical machines (induction and synchronous machines) and of bearing currents. The failure analysis includes: – interturn faults; – phase-to-phase short-circuits; – double earth faults and single earth faults of motors with earth connection of the starpoint; – static and dynamic eccentricities; – cage imperfection or defects (e.g. broken bars or end-rings); – bearing currents. This can be achieved by tools like search coils or other magnetic sensors or partly by the analysis of the terminal voltages and currents. The detection of the following effects is excluded from the scope: – vibration (covered by ISO standards, e.g. ISO 10816 and ISO 7919); – partial discharge (covered by IEC 60034-27); – single earth-faults of motors without earth connection of the star-point; – core imperfection. Also excluded are special methods applicable for specific applications only (e.g. turbo generators).

This part of IEC 34 identifies the circuit arrangements and the methods of movement of the coolant in rotating electrical machines, classifies the methods of cooling and gives a designation system for them. The designation of the method of cooling consists of the letters "IC", followed by numerals and letters representing the circuit arrangement, the coolant and the method of movement of the coolant. A complete designation and a simplified designation are defined. The complete designation system is intended for use mainly when the simplified system is not applicable. The complete designations, as well as the simplified designations, are illustrated in the tables of annex A for some of the most frequently used types of rotating machines, together with sketches of particular examples.

This International Standard, which forms part of the ISO 8528 series, specifies criteria, including performance and test methods, for rotary uninterruptible power systems (UPS) arising out of a combination of mechanical and electrical rotating machines. This standard applies to power supplies primarily designed for supplying uninterrupted a.c. power to the consumer. When operated without input mains feed, the power is provided by stored energy and/or reciprocating internal combustion (RIC) engine and the output power is provided by one or more rotating electrical machines. This part 11 applies to a.c. power supplies primarily designed for supplying uninterruptible electrical power for stationary land and marine use, excluding supplies for aircraft, land vehicles or locomotives. It also excludes power supplies where the output power is generated by static converters. (See IEC 62040-3.) The use of a rotary UPS installation to improve the quality of a.c. power supply, to provide voltage and/or frequency conversion, and to provide peak shaving is also described. For some specific applications (for example, essential hospital supplies, offshore, non-stationary applications, high rise buildings, nuclear, etc.) supplementary requirements may be necessary. The provisions of this part of ISO 8528 should be used as a basis.
