3 Terms and definitions
Replace the existing definitions with the following new definitions:
3.11
impulse voltage repetition rate
f
average of the inverse of the time between two successive impulses of the same polarity,
whether unipolar or bipolar, in a considered set of pulses, for example for one period
3.18
impulse voltage insulation class for Type II insulation systems
IVIC
peak to peak voltage classes 1, 2, 3, 4, 5, 6, 7, S including certain time parameters for reliable
operation, assigned by the manufacturer in relation to the rated voltage for a specified
converter-driven machine and indicated in its documentation and, if applicable, on its rating
plate
3.29
maximum allowable peak to peak phase to ground voltage
U
IVIC
maximum allowable peak to peak phase to ground voltage in service, according to the IVIC-
specification
IEC 60034-18-42:2017/AMD1:2020 – 3 –
© IEC 2020
Add the following new definition:
3.30
test voltage factor
TVF
maximum allowable peak to peak operating phase-ground-voltages in units of U , divided by
N
2√2
Replace the existing Table 1 with the following:
Table 1 – Examples of the measured values of the characteristics
of the terminal voltages for two converter-fed machines
Machine rating 3,3 kV 6,6 kV
Measured peak to peak voltage on the phase to ground insulation 7,9 kV 13,9 kV
Fundamental frequency 50/60 Hz 50/60 Hz
Impulse rise time at the motor terminals 1 µs 3 µs
Impulse repetition rate 1 kHz 900 Hz
IVIC required to qualify the insulation for this service (see Table D.2, column 2) 3 2

Replace the second paragraph below Table 1 with the following:
The maximum change in voltage or jump voltage (U ) at the impulse repetition rate is shown in
j
Figure 3. This parameter is important in defining the voltage enhancement that can occur across
the first or last coil in the winding. A fundamental frequent double jump transition
(Figure 3, U )) is possible and needs to be considered accordingly.
