Each coil of three phases has two terminals (one 'start' and another 'finish') and if individual phase is connected to a separate load circuit, as illustrated in Fig. 7.3, we get a non-interlinked three- phase, six-wire system. Then, by Ohm's law, the current in individual phase will be: IP = EP/ZP … (7.4) Where Ip is the phase current, Ep [...]
