Environment

Resolution
Yes, PM5000 series can be wired as a high leg delta with the system type as 3-phase 4-wire center-tapped delta.
In addition, the PM5000 series meter can be set to 3-phase 4-wire open center-tapped delta in a case of a three-phase load is small relative to the total load.
In this case, two individual transformers may be used instead of the three for a "full delta" or a three-phase transformer.
The PM5000 series can support all the power system listed below in table. For the wiring diagram, refer to the installation guide for each model of PM5000 series.
