Power Factor Calculation (Pf) - Chauvin Arnoux F 09 Manual De Instrucciones

In both cases the "
directed in the direction of power circulation from the
source to the load. In which case:
- the "+" sign corresponds to power consumed by the
load.
- the "-" sign corresponds to power supplied by the load.

1) the scale is limited to 240 kW (kvar, kVA) in one-phase
(
(600 V x 400 A) and 399.9kW (kvar kVA) in 3 phases system.
Above this value, the display indicates +OL or -OL depending
on the sign of the power.
(2) if the power value is < 5 W or if the voltage or current
values are respectively < 0.15 V or < 0.15 A, 0 is displayed.
(3) The measurement accuracy is affected by an instability
linked to current measurement of approximately 0.1 A.
Example: for a power measurement performed at 10 A, the
instability of the measurement will be 0.1 A/10 A, or 1%.
MIN/ MAX Mode:
- Accuracy: same as previous table +0.3% L
- Capture time: 100 ms typ. (every 400 ms)

3.9 Power factor calculation (PF)

With the clamp configured in power measurement (switch
on position W) and correctly connected (see § 3.8), perform
a short press on the yellow key: the power factor is displayed.
The power factor is, by definition, an unsigned quantity,
however, a sign is displayed showing whether the charge is
inductive ("+" sign) or capacitive ("-" sign). This sign is
significant only in the case of slightly distorted signals (i.e. 3
switches to zero over 1 period).
