	What is the advantage of connecting VFD loads to Dyn11Zn0 transformer? I would like to know the applications of transformers based on different vector groups and the reasons for selection. Where can i get these details? __________________ jayesh b sathwara

	VFD operation produces lots of harmonic in the system. These harmonic components induces current in the Delta winding of the transformer and get circulated in the winding. Delta winding reduces the harmonic components and thus keep the system stable. Sidhu
