6 Wire Open Delta
6 Wire Open Delta
(OP)
I am trying to come up with a source/method to 3 phase 6 wire open delta 115VAC 400HZ power to a product. My experience is more on the electronics side. I have access to 3PH 400Hz Wye power. How do you convert. Is is as simple as 3 1PH ISolation transformers?

IEEE C57.12.70 §8 lists some six-phase "star" and "double-delta" configurations, but nothing "6ø open." Consultant/RFI time?

tberry — The "6 Wire Open Delta" illustration on page 3 of jbartos' link http://www.fastron.com.au/pdf/f330-cat.pdf along with your description seems to point to flexibility in operating the device as either 200Y/115V 4-wire wye, or 115V 3-wire delta. The US military has used both, but I don’t know if 115V∆ configuration is still used. If this is indeed the case, the device MAY possibly be able to be powered by a 4-wire 208Y/120V circuit.
