Wiring plan, connecting
the voltage and current
inputs to power network.
The application of:
The vectorsum of all phase
voltages is always zero!
The terminal "k" of CT and
terminal "v" of VT you have
to connecting to earth!

5.6. Connecting the measuring inputs
three-phase power network with neutral conductor.
(3 phase, 4 wire, 1 measuring)
The following figure shows the wiring plan to symmetrical
three-phase network. Measuring only one phase. The three
phase outputs are calculated values. The measuring
arrangement use for the measurement of rotating
machinery!
1. Loosen terminal screws.
2. Insert the wire ends into the open terminals according to
the wiring plan.
3. Screw the terminal in.
4. Check the hold of the wires in terminals by pulling on
them firmly.
Check if the cables are connected properly (have you
connected all the cables, have you connected to the right
place, do not the cable-ends touch each other).
