Hemodynamics in Hemofiltration,of induced e.m.f.s the arrows indicate the positive direction of the e.m.f. for each particular phase. If all three phases were kept separate a six-conductor line between source and load would be necessary. By interconnecting the phases the number can be reduced to three; in one special case four. There are two methods.
