The paralleling gets simple when those two generators are from the same manufacturer and of the same power output. Moreover, it gets even more simple when the generators are parallel capable.In a three-phase, Y-connected alternator, the total voltage, or line voltage, across any two of the three line leads is the vector sum of the individual phase voltages. Each line voltage is 1.73 times one of the phase voltages. Because the windings form only one path for current flow between phases, the line and phase currents are the same (equal).On the background there is the three-phased transmission network. This is wired by three separate wires that normally hang adjacently along rows of poles. The voltage between each wire is 11kV, and the waveform graph drawn for each wire's voltage (and current too) are one third of a cycle off each other.A single-phase power supply uses two wires to provide a sinusoidal voltage. In a three-phase system, three wires are used to provide the same sinusoidal voltage, but each phase is shifted by 120°. At any point in time, if you were to add up the voltage of each phase, the sum would be constant.When generating 3 phase power, the copper lines are located 120 degrees apart. So when you're at the four o'clock position in our example here, that's 120 degrees away from line one. And at the eight o'clock position is 120 degrees away from both the 4 and 12 o'clock positions. The 3 lines are equally spaced around the circle.How does a 3-phase generator work? With the three different coils, a 3-phase generator can produce 3 distinct power waves in a sequence. This means that throughout its use, a 3-phase generator provides a continuous power flow. It concurrently means that the power will never subside to zero, a problem that happens a lot with single-phase generators. what does a caller hear when their number is blocked on a landline 120/240V is standard single phase (2 pole).
