Three-phase High-leg delta

Three-phase high-leg delta installation measuring power coming from a power utility (grid).

Registers:

Notes:

•  Wiring and configuration is identical to a standard three-phase site. The only difference is in the voltages measured on L1, L2, and L3: – L1 and L3 are 120Vac to neutral. – L2 is 208Vac to neutral. 
• It does not matter whether the high-leg is wired to L1, L2, or L3, as long as all three phases are measured.
