Good morning team,
Looking for a quick refresher on transformer selection and how it correlates to fault current contribution to a grid. Is there a major benefit in selecting a delta-delta or delta-wye or wye-delta or wye-wye when trying to limit the fault contribution. Im seeing more...
Looking for confirmation on zero sequence philosophy as it pertains to Distributed Energy Resources. I am converting a site with multiple meters to a singular main primary PCC/primary service point. I am creating the protection scheme which is pretty much done but was told im still lacking zero...
Hey all,
Trying to export to the grid through a step up transfer but gens are tripping on a kVar imbalance. I believe there isIs anyone aware of any equipment i can install at the generator to minimize or eliminate phase imbalance?
