Current Connections
Connect the current leads from the Calibration System Input/Output Panel to the UUT as
follows (refer to Figure 4-2).
Note
Most PMUs will have a visual current flow indicator (usually a “sense” or
“phasing” dot) above the current input connectors. To prevent inaccurate
UUT measurements, make sure to connect the red current wires to the
current inputs with the current flow indicator. This will make sure that the
current flow is in the same direction for all three current phases.
1. Connect the
Red
current wire to the
Red Current HI Output
.
2. Connect the
Black
current wire to the
Black Current LO Output .
On the rear panel of the UUT for each phase in turn:
1.
Connect the
Red
current wire to the
Current Input
(input with the current flow
indicator).
2. Connect the
Black
current wire to the
Current Input
(input without the current flow
indicator).
