Can anyone provide me with information regardingthe conversion of 60Hz to 50Hz. I presently have 1500 KVA utility service into a Seimens 3000A switch board. I draw some of this power off to run a 600A panel. I also channel power through a transformer to step up voltage to 4160/7200v which I use for testing construction equipment. I need to simultaneously test 60 & 50Hz equipment. Is there a way to tranfer some of my power from my switchboard to a piece of equipment that would convert the 60Hz to 50Hz so I can run this into another transformer and step it up to the needed voltage? What type of equipment is necessary? Any links that you can think of to guide me in this process? Thanks!
