Note about EN and IEC standards:
Text of this manual contains references to European standards. All standards of EN
6XXXX (e.g. EN 61010) series are equivalent to IEC standards with the same number
(e.g. IEC 61010) and differ only in amended parts required by European harmonization
procedure.
1.4 Abbreviations
In this document following symbols and abbreviations are used:
CF
I
Current crest factor, including CF
Ip
(phase p current crest
factor) and CF
IN
(neutral current crest factor). See 5.1.3
for definition.
CF
U
Voltage crest factor, including CF
