    Application requires the installation of a power meter or replacement existing meter in a high leg delta system.

    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 indicidual transformers may be used instead of the three for a "full delta" or a three-phase transformer.
