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.

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
Upg
(phase p to phase g voltage
crest factor) and CF
Up
(phase p to neutral voltage crest factor). See

DPF
ind/cap
Instantaneous phase power displacement (fundamental) power
factor or cos
, including
DPFp
ind
(phase p power displacement).
Minus sign indicates generated power and plus sign indicates
consumed power. Suffix ind/cap represents inductive/capacitive
character.
DPF
ind/cap
Recorded phase displacement (fundamental) power factor or cos
,
including DPFp
ind/cap
(phase p power displacement).
Minus sign indicates generated
power and plus sign indicates
consumed power. Suffix ind/cap
represents inductive/ capacitive
character. This parameter is recorded
separately for each quadrant as
shown on figure. See 5.1.5 for
definition.
DPFa
totind
DPFa
totcap
Instantaneous total arithmetic displacement (fundamental) power
factor.
Minus sign indicates generated power and plus sign indicates
consumed power. Suffix ind/cap represents inductive/capacitive
character. See 5.1.6 for definition.
