Application
Iprim: Primary current from 2kV AC output,
measured by the CPC 100 internally
If the focus is on the table, scrolling
through the lines will change this
display accordingly, depending on the
selected line.
The ° shows the phase angle of the
primary current relative to Vprim
nominal.
Tap (in table): Displays the transformer tap identifier
and tap number for the measurements
in the respective line of the table.
Vprim: Actual voltage injected from
AC OUTPUT into the transformer’s
high-voltage side
Vsec: Actual voltage measured at V1 AC
from the transformer’s low-voltage
side.
The ° shows the phase angle of the
primary current relative to Vprim
nominal.
Note: Even on transformers such as
Yd5, only phase angles like 0° or 180°
can be found using a single phase test
set because a transformer can change
the phase angle only by "mixing"
different phases.
Ratio :1 Calculated ratio value from the
measured values Vprim / Vsec
%: The % shows the deviation of the
actual ratio from the nominal ratio in
%.
