Unbalance
Introduction
Unbalance displays phase relations between voltages and currents. Measuring results are
based upon the fundamental frequency component (60 or 50 Hz). In a 3-phase power
system, the phase shift between voltages and between currents should be close to 120°.
Unbalance mode offers a measurement table, a related Trend display, and a Phasor
display.
