INTERNATIONAL ELECTROTECHNICAL COMMISSION
ROTATING ELECTRICAL MACHINES -
Part 15: Impulse voltage withstand levels of rotating a.c. machines
with form-wound stator coils
FOREWORD
The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
1)
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation on all questions concerning standardization in the electrical and
electronic fields. To this end and in addition to other activities, the IEC publishes International Standards.
Their preparation is entrusted to technical committees; any IEC National Committee interested in the
subject dealt with may participate in this preparatory work. International, governmental and
non-governmental organizations liaising with the IEC also participate in this preparation. The IEC
collaborates closely with the International Organization for Standardization (ISO) in accordance with
conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
3) They have the form of recommendations for international use published in the form of standards, technical
reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
International Standard IEC 34-15 has been prepared by IEC technical committee 2:
Rotating machinery.
This second edition cancels and replaces the first edition published in 1990 and
constitutes a technical revision.
The text of this standard is based on the following documents:
Reports on voting
DIS
2(CO)577 2(CO)587A
2(CO)587B
Full information on the voting for the approval of this standard can be found in the reports
on voting indicated in the above table.

INTRODUCTION
IEC 71-1 specifies general requirements for the phase-to-earth insulation of equipment
in three-phase a.c. systems and states that each apparatus committee is responsible
for specifying the insulation levels and test procedures for its equipment, taking into
consideration the recommendations of IEC 71-1. The object of this standard is to specify
requirements for rotating electrical machines and experience has shown that the values
given in this standard meet the insulation requirements for the essential stresses in
service under usual operating conditions. An explanation of the principles adopted in
preparing these requirements is given in annex A.

ROTATING ELECTRICAL MACHINES -
Part 15: Impulse voltage withstand levels of rotating a.c. machines
with form-wound stator coils
1 Scope
This part of IEC 34 specifies the rated phase-to-earth impulse voltage withstand levels
of rotating a.c. machines having rated voltages from 3 kV to 15 kV inclusive and
incorporating form-wound stator coils, together with the test procedures and voltages to be
applied to the main and interturn insulation of sample coils to prove the compliance of the
machine.
2 Normative references
The following normative documents contain provisions which, through reference in this
rt
text, constitute provisions of this pa of IEC 34. At the time of publication, the editions
indicated were valid. All normative documents are subject to revision, and pa rties to
of IEC 34 are encouraged to investigate the possibility of
agreements based on this pa rt
applying the most recent editions of the normative documents indicated below. Members
of IEC and ISO maintain registers of currently valid International Standards.

3 Definitions
For the purpose of this pa rt of IEC 34 the following definitions apply.
3.1 random sample test: Test carried out on coils which adequately represent the
configuration of the finished item to be used in the machine, for the purpose of evaluating
the basic design, type of materials, manufacturing procedures and processes incorporated
in the insulation system.
3.2 routine test: Test carried out on all coils of the machine.
3.3 form-wound stator coil: Coil which is preformed to shape before insertion into the
stator.

4 Impulse voltage withstand levels
Rated impulse voltage withstand levels for rated voltages from 3 kV to 15 kV shall be
obtained by application of the formulae given in notes 2 and 4 of table 1, the values
obtained being rounded off to the nearest whole number. Table 1 gives the rated impulse
voltage withstand levels for some common rated voltages, together with the corresponding
rated power-frequency withstand voltage (r.m.s.) according to IEC 34-1.
