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.
