8.4 SUPPORTED ELECTRICAL NETWORKS
The following types of distribution networks are supported: – Single phase
(single phase 2-wire 1 current) – Single phase (single phase 3-wire 2
currents) – Split-phase (split-phase single phase 3-wire)
V1, V2 are the phase-neutral voltages of the installation measured. [V1=VL1-N;
V2=VL2-N].
The lower case letters v1, v2, v3 denote the sampled values. U12 is the
voltage between phases of the installation measured. Lower case letters denote
the sampled values [u12 = v1-v2]. I1, I2 are the currents flowing in the phase
conductors of the installation
measured. The lower case letters i1, i2, i3 denote the sampled values.
