Total non-active power :
A.1.4.2 THREE-PHASE SYSTEM WITHOUT NEUTRAL
Three-phase distribution systems without neutral are considered as a whole (no phase-by-phase power calculation). The
device therefore displays only the total quantities. The two-wattmeter method (Aron method or two-element method) is
applied for the calculation of the total active power, of the total reactive power and of the total DC power.
