The customer has limitation on main 11kv/430V transformer on capacity . Now if he keeps all his 415V vfds online he is having harmonic and the load on vfd is also runs full speed . So we wanted to transfer to mains on the fly from VFD .The benefit is lower harmonics at PCC , additional capacity...
Hello,
I need to transfer motor once it reaches 50Hz i.e 100% speed on vfd to mains .The same needs to carried out for FC102 , ACS850 , ACS550 , ACS800 . I hear the synchronous transfer option exists for ACS800 . Danfoss has agreed to offer synchronous card (which is still in R&D ) .My going...
