3 Phase, 3 probe Delta
The figure below shows the 3 Phase, 3 probe, 2 wattmeter delta
connection using phase channels A-B-C. The N channel is chosen as the
reference and is connected to phase B for measurement purposes.
Current probes are connected to measure line currents A, B and C. Note
that the B current probe is connected to measure the B phase current
only and is not included as part of the power computations.
NOTE Be sure to connect the current probes with the arrow
pointing towards the load or an erroneous power reading
will result.
