The purpose of this document is to provide technical guidance for tests on generating units and interface protection to evaluate their electrical characteristics.
NOTE 1    Mechanical issues are taken into account as far as they influence the electrical characteristics.
The evaluation results are intended to be used to demonstrate conformity of generating units to technical requirements for grid connection. In this context the evaluation results can also be used as part of a certification programme.
NOTE 2    Besides the type test results of the generating unit all additional elements for connection to the grid (e.g. transformer, cabling, multiple units) are considered in the evaluation of the final installation of a generating plant.
The requirements to be evaluated are covered in the following standardization documents:
–   EN 50549 1:2019: Requirements for generating plants to be connected in parallel with distribution networks - Part 1: connection to a LV distribution network - Generating plants up to and including Type B
–   EN 50549 2:2019: Requirements for generating plants to be connected in parallel with distribution networks - Part 2: Connection to a MV distribution network - Generating plants up to and including Type B
If grid connection requirements are dealt with in other documents or for other generating module types, where no specific testing procedure is provided, testing methods of this document can be used if applicable.
This document provides evaluation criteria for the conformity assessment of generating units with respect to the above mentioned standardization documents, based on type testing. However, some requirements are applicable on the generating plant level. The assessment of the conformity to these plant requirements are out of the scope of this document. Nevertheless, this document may be used to show the capabilities of a generating unit to be used in a plant.
As a consequence, it is possible that the conformity assessment of a generating unit does not cover all aspects of the above-mentioned standardization documents, typically when a requirement is evaluated on a plant level. Therefore, the conformity assessment report indicates clearly which clauses of this document are covered and which clauses are not covered.
This document recognizes the existence of specific technical test requirements within several member states that must be complied with.

This document provides guidelines for the assessment of torsional natural frequencies and component strength, under normal operating conditions, for the coupled shaft train, including long elastic rotor blades, of steam and gas turbine generator sets. In particular, the guidelines apply to the torsional responses of the coupled shaft train at grid and twice grid frequencies due to electrical excitation of the electrical network to which the turbine generator set is connected. Excitation at other frequencies (e.g. subharmonic frequencies) are not covered in this document. No guidelines are given regarding the torsional vibration response caused by steam excitation or other excitation mechanisms not related to the electrical network. Where the shaft cross sections and couplings do not fulfil the required strength criteria and/or torsional natural frequencies do not conform with defined frequency margins, other actions shall be defined to resolve the problem. The requirements included in this document are applicable to a) steam turbine generator sets connected to the electrical network, and b) gas turbine generator sets connected to the electrical network. Methods currently available for carrying out both analytical assessment and test validation of the shaft train torsional natural frequencies are also described. NOTE Radial (lateral, transverse) and axial vibration of steam and/or gas turbine generator sets is dealt with in ISO 20816-2.

This document specifies methods and procedures for determining the static performance of particulate air filters used in air intake filter systems for rotary machinery such as stationary gas turbines, compressors and other stationary internal combustion engines. It applies to air filters with an efficiency of 85 % or more for the MPPS (EPA and HEPA filters) which are tested according to ISO 29463 (all parts) and filters with a lower efficiency which are tested according to ISO 16890 (all parts). The procedures described in both ISO 16890 (all parts) and ISO 29463 (all parts) are applied and extended by this document to air filters which operate at flow rates within the range 0,24 m3/s (850 m3/h) up to 2,36 m3/s (8 500 m3/h).
Static filter systems normally use multiple stages of coarse, fine and optional EPA or HEPA filter elements to protect the machinery. The scope of this document includes methods for performance testing of individual filter elements. It does not include methods for the direct measurement of the performance of entire systems as installed in service except in cases where they can meet the qualification criteria for the test assembly. Nevertheless, cumulative filter efficiencies of multistage systems of fine filters can be calculated by using the methods described in ISO 16890-1.
This document refers to static (barrier) filter systems but can also be applied to other filter types and systems in appropriate circumstances, for example to evaluate the initial efficiency of cleanable and surface loading filters.
The performance results obtained in accordance with this document cannot be quantitatively applied (by themselves) to predict performance in service with regard to efficiency and lifetime.

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.

This document specifies methods and procedures for determining the static performance of particulate
air filters used in air intake filter systems for rotary machinery such as stationary gas turbines,
compressors and other stationary internal combustion engines. It applies to air filters with an efficiency
of 85 % or more for the MPPS (EPA and HEPA filters) which are tested according to ISO 29463 (all parts)
and filters with a lower efficiency which are tested according to ISO 16890 (all parts). The procedures
described in both ISO 16890 (all parts) and ISO 29463 (all parts) are applied and extended by this
document to air filters which operate at flow rates within the range 0,24 m3/s (850 m3/h) up to
2,36 m3/s (8 500 m3/h).
Static filter systems normally use multiple stages of coarse, fine and optional EPA or HEPA filter elements
to protect the machinery. The scope of this document includes methods for performance testing of
individual filter elements. It does not include methods for the direct measurement of the performance
of entire systems as installed in service except in cases where they can meet the qualification criteria
for the test assembly. Nevertheless, cumulative filter efficiencies of multistage systems of fine filters
can be calculated by using the methods described in ISO 16890-1.
This document refers to static (barrier) filter systems but can also be applied to other filter types and
systems in appropriate circumstances, for example to evaluate the initial efficiency of cleanable and
surface loading filters.
The performance results obtained in accordance with this document cannot be quantitatively applied
(by themselves) to predict performance in service with regard to efficiency and lifetime

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 60034-4-1:2018 applies to three-phase synchronous machines of 1 kVA rating and larger and describes methods intended to be used for machines having an excitation winding with slip-rings and brushes for their supply. Synchronous machines with brushless excitation require special effort for some of the tests. For machines with permanent magnet excitation, there is a limited applicability of the described tests, and special precautions should be taken against irreversible demagnetization.
