Grounding of generator neutral:
Generator: 1 MW; 3 phase; 600 V is connected to grid through interface transformer: 1.5 MVA; 27.6 kV star solid gnd/600 V star solid gnd and exports power to grid.
How the generator neutral should be grounded? a) Solid; b)Low impedance; or c) High impedance. If...
Distributed Generation: What should be the preferred interface transformer's winding configuration (utility side Delta, Star solid grd, or Star effectively grd. a) preferred by utility; b) preferred by generating facility. However I am interested in utility's preference particularly when...
