Step 1 - Voltage from L3 to ground should read close to 220 volts, this is correct, the output of a phase converter is a delta three phase voltage, if a neutral or 120 ground is needed from all three lines, a delta-wye transformer is required.
I measure 120 volts from L1 and L2 to ground, but 220 volts from L3 to ground. Print
