No. The japanese verified it as well. L2 is a nuetral, grounded at the transformer in a delta configuration. I don't understand it, how L2 can be nuetral in a 3 phase system. Also,if I dropped a phase, the 3 phase motor and compressor would be single phasing and making troubles.
Thanks for...
Ok that makes sense. Now what about this:
When I measure L1 to ground I get 220 voltage when I measure L2 to ground I get 0 and when I measure L3 to ground I get 200. How can L2 to ground be 0 if its 3 phases? I am in Japan by the way. Thanks for any help.
Thanks, that clears it up a bit. But how do you get 240 from that? I can see how L1 is finding its potential when L2 goes negative. when the top of the wave at L1 is at peak value, is that 120? if so, how can the total voltage be 240? If the bottom of the wave at L2 is only a potential, it would...
I am servicing a machine that uses a 3 phase power supply. Some of the components (motor, compressor, fan) use 3 phase power. Other components (solenoids) use single phase (phase to phase) tapped from L1 and L3. I understand regular single phase-120v and a nuetral. The nuetral creates the...
