Unbalance; Introduction; Phasor Screen - Fluke 434-II User Manual

Introduction

Unbalance displays phase relations between voltages and currents. Measuring results are
based upon the fundamental frequency component (60 Hz, 50 Hz, or 400 Hz in Fluke
437-II) using method of symmetrical components). In a 3-phase power system, the phase
shift between voltages and between currents should be close to 120°. Unbalance mode
offers a Meter screen, a related Trend display, Events tables, and a Phasor display.
