Delta Synchro/Power Monitor Connection (Two Wattmeter
Method)
This diagram illustrates the wiring of an open delta system utilizing the two-wattmeter
method of measurement. When used for paralleling the two grids, the missing voltage and
current inputs must be configured as unused, so the PSM can reconstruct those signals
Fuses on the PT primaries and secondaries are required. A fuse failure is an indication of
wiring problems within the system.
