Comment

1P2W

Single-phase measurement,

2 conductors

Measuring the load in an AC network with a

current and a voltage converter

Energy Meter supplies the value "0" for all

measured values of Phases 2 and 3 as well

as for some cross-phase measured values.

3 x 1P2W

3 x single-phase measure-

ment

Measurement with three current transform-

ers for any three loads that are each con-

nected to one of the three phases

Max. permissible secondary current of the

current transformer is 1 A
