Parameter Options Description
Phase Angle Error +/-600 minutes The phase displacement, in minutes, between
the primary and secondary values. The phase
angle of a transformer is positive when the
secondary value leads the primary value.
You can define a total of 56 correction points for ratio and
phase correction data - up to 8 test points per voltage and
current channel, based on the transformer’s accuracy
characteristics. If more than one test point is given for a
channel, the meter dynamically interpolates to the actual
operating point depending on the measured voltage or
current. When a single test point is defined, it is applied over
the full operating range of the transformer.
The order in which you define the test points does not
matter. The meter will automatically arrange all data in a
correct order.
Check the Correction Enabled box to activate transformer
correction in the meter. You can also enable and disable
transformer correction from the front display (see
Device
Options and Mode Control ).
Transformer/Line Loss Compensation Setup
Loss compensation corrects the power and energy readings of
the meter when the metering point and point of billing are
physically separated by a power transformer or a power line.
Select General Setup from the Meter Setup menu, and then
click on the Transformer/Line Loss Compensation tab.
