25-50 ANALIZA PUTERILOR ACTIVE ALE UNUI RECEPTOR TRIFAZAT


THE ACTIVE POWERS ANALYSIS OF A THREE-PHASE LOAD
In this paper we consider a three-phase load and the absorbed powers
by it. We define the real unbalanced load, which has a balanced part and an
extremely unbalanced part. Using the complex power absorbed by the threephase
load, we make the actiwe powers analysis of it. Also, we construct the
energetical diagrams about the active powers circulation and are presented the
conclusions. In the end of the paper we indicate the references.
