This part of IEC 60034 provides a common basis for: - measuring techniques and instruments; - the arrangement of test circuits; - normalization and testing procedures; - noise reduction; - the documentation of test results; - the interpretation of test results, with respect to partial discharge off-line measurements on the winding insulation of rotating electrical machines. The measurement methods described in this document are applicable to stator windings of machines with or without conductive slot coating and to the stator windings of machines made with form wound or random wound windings. In special cases like high voltage rotor field windings, this document is applicable as well. The measurement methods are applicable when testing with alternating sinusoidal voltages from 0,1 Hz up to 400 Hz. Interpretation guidelines are given in this document and are applicable only if all the following requirements are fulfilled: - Measurements performed with power frequency of 50 Hz or 60 Hz, or when testing with power supply within a frequency range of 45 Hz to 65 Hz. - Form wound windings and winding components such as bars and coils. - Winding with conductive slot coating. This is usually valid for machines with voltage rating of 6 kV and higher. For machines with random wound windings, form-wound windings without conductive slot coating, and testing at frequencies differing from power frequencies, the interpretation guidelines are not applicable. The testing procedures for off-line PD-measurements of this document can be used for assessing the uniform quality of manufacturing or/and the trending of these kind of windings as well as converter driven machine windings. NOTE Testing of low voltage machines with so called Type I insulation systems is defined in reference [10]1. Testing procedures for qualification of converter driven high voltage machines with so called Type II insulation systems are dealt with in IEC 60034-18-42 (in addition to the optional electric tests described therein).

IEC SRD 62913-2-1 2019 (E) initiates and illustrates the IEC’s systems approach based on Use Cases and involving the identification of generic smart grid requirements for further standardization work for grid related domains – i.e. grid management regrouping: transmission grid management, distribution grid management, microgrids and smart substation automation domains – based on the methods and tools developed in IEC SRD 62913-1.
The Grid management domain groups Use Cases and associated requirements common to the EHV, HV and MV/LV networks operations and the business analysis of the general electric network life cycle. Use Cases specific to parts of the general electric network are described in transmission grid management, distribution grid management, microgrids and smart substation automation clauses.
This document captures possible “common and repeated usage” of a smart grid system, under the format of “Use Cases” with a view to feeding further standardization activities. Use Cases can be described in different ways and can represent competing alternatives. From there, this document derives the common requirements to be considered by these further standardization activities in term of interfaces between actors interacting with the given system.
To this end, Use Case implementations are given for information purposes only. The interface requirements to be considered for later standardization activities are summarized (typically information pieces, communication services and specific non-functional requirements: performance level, security specification, etc.).

This part of IEC 60034 covers the procedures necessary to ensure the satisfactory repair, overhaul, and reclamation of all types and sizes of rotating electrical machines covered by the IEC 60034 series. The standard creates a generic industry procedure covering common aspects of a complete repair. The scope of work depends on the machine type, rating, condition, and the importance of plant reliability and safety. It includes
- determining cause of failure, where necessary;
- determining the extent of repair, as applicable;
- defining revised performance, operating and ambient conditions, if required;
- reviewing the original design, and upgrading the specification of the design, if required;
- proving the quality and performance of the repaired machine, maintaining or improving the rated energy efficiency;
- ensuring environmental considerations are taken into account.
This document does not supersede the requirements prescribed in IEC 60079-19 or elsewhere concerning the repair and overhaul for machines used in explosive atmospheres.
Machines for special applications such as hermetic, submersible, nuclear, hydrogen cooled machines, military, aviation and traction motors might have additional requirements, which are the subject of agreement between the service facility and user.
This document is not intended to take the place of the original machine manufacturer’s instructions and recommendations.
Re-designs and performance changes requiring machine designer input are beyond the scope of this document.
