HARNESS GP-WRG 3669476 - Caterpillar

Illustration 1 g00584153
Open Delta Configuration of External Potential Transformers on Three-Wire Delta GeneratorThis configuration allows the GSC+ to accurately measure power parameters when loads are unbalanced and when circulating current is present. The following real power phases cannot be determined: phase A, phase B and phase C. The following power factor phases cannot be determined: phase A, phase B and phase C. These phases are not shown on the GSC+ display.
Illustration 2 g00584154
Open Delta Configuration of External Potential Transformers on Four-Wire Wye GeneratorThis configuration does NOT allow the GSC+ to measure all power parameters when loads are unbalanced and neutral current is present. The following real power phases cannot be determined: phase A, phase B and phase C. The following power factor phases cannot be determined: phase A, phase B and phase C. These phases are not shown on the GSC+ display.
