MEASURING POWER IN 3-PHASE BALANCED
SYSTEMS.
The Fluke 43B can perform power measurements on 3-phase, 3-conductor
balanced power systems. The load must have approximately the same voltage
and current on all three phases, and must be wired in a wye or delta
configuration.
The balanced load makes it possible to calculate 3-phase power from one
current and one voltage channel. Three phase power measurements are
possible for the fundamental only.
