IEC 63129:2020 pdf free download Determination of inrush current characteristics of lighting products
This document describes a method, based on measurements combined with calculations, todetermine specific characteristics of the inrush current of single and/or multiple lighting productsof the same type. Lighting products include the following:
. light sources with integrated controlgear,
.controlgear,
. luminaires.
The inrush current characteristics that are determined are.the peak inrush current,
the inrush current pulse duration.
This document applies to lighting products connected to low-voltage 230 V AC 50/60 Hzelectrical supply networks.
NOTE In Clause 6 it is stated that the methodology applies reference values for the reference (line) inductance andthe reference (short circuit) peak current which reflect the typical situation in a 230 v AC installation.

3.1
bidirectional diode thyristorDIAC
two-terminal thyristor having substantially the same switching behaviour in the first and thirdquadrants of the current-voltage characteristic
[SOURCE: IEC 60050-521:2002,521-04-66]
3.2
bidirectional triode thyristorTRIAC
three-terminal thyristor having substantially the same switching behaviour in the first and thirdquadrants of the current-voltage characteristic
3.3
circuit-breaker
mechanical switching device, capable of making, carrying and breaking currents under normalcircuit conditions and also making, carrying for a specified duration and breaking currents underspecified abnormal circuit conditions such as those of short circuit
[SOURCE: IEC 60050-441:2000,441-14-20]
3.4
control gearcontrolgear
<for an electric light source> unit inserted between the power supply (IEV 151-13-75) and atleast one light source, which serves to supply the light source(s) with its (their) rated voltage orrated current, and which can consist of one or more separate components
Note 1 to entry: The control gear can include means for igniting,dimming,correcting the power factor andsuppressing radio interference, and further control functions.
Note 2 to entry: The control gear consists of a power supply (IEV 151-13-76) and a control unit.Note 3 to entry: The control gear can be partly or totally integrated in the light source.
Note 4 to entry: The terms “control gear”and “controlgear”are interchangeable.In lEC standards,the term”controlgear” is commonly used.

3.5
Linrush
inrush current
transient current associated with energizing of electrical apparatus or components
EXAMPLE Lighting products, transformers, cables, reactors.
