Description
The model PF5 provides a dc
output which is linearily proportional
to the phase angle diffence
between voltage and current
of an ac power system. The polarity
of the bipolar output indicates
leading or lagging conditions.
Balanced
load conditions are necessary
in three-phase systems. Deviation
from sine wave conditions leads
to inaccuracies with all transducers
since angle measurement is based
on time difference between zero
crossings.

Applications
- Provides
an accurate means for calculating
power factor, PF =COSØ.
