It's a self starting 15hp 3 phase motor with a heavy iron frame that I built using a potential relay and some start caps to get it running and I have 120uf (two 60's) run caps between phase 1 and 2, and 60uf between phase 2 and 3. The incoming single phase legs are connected to phase 1 and 3.
The voltages to ground are 1 = 120v, 2 = 210v, 3 = 120v. Phase to phase they are 1 + 2 = 243v, 2 + 3 = 238v, 1 + 3 = 244v While we are at it the voltage readings on the 380v side of the three phase transformer that is in the machine are: to ground 1 = 209, 2 = 302, 3 = 213 phase to phase 1 + 2 = 386, 2 + 3 = 378, 1 + 3 = 388 At terminals UVW (U=1, V=2, W=3) on the infeed module are the following voltages: to ground U = 478, V = 530, W = 472 phase to phase U + V = 650, U + W = 646, U + W = 648 Thanks John Thornton On 5/9/2012 8:26 AM, Dave Caroline wrote: > How does your phase converter work (which method) > any inbalance in phase or waveform will effect stuff downstream > > Dave Caroline > > ------------------------------------------------------------------------------ > Live Security Virtual Conference > Exclusive live event will cover all the ways today's security and > threat landscape has changed and how IT managers can respond.
