Other three-phase voltages, up to 830 volts, are occasionally used for special-purpose systems such as oil well pumps.
12.
The relative magnitudes of the two-phase voltages are measured and used to determine the angle of the rotor relative to the stator.
13.
The single-phase voltage source half-bridge inverters, are meant for lower voltage applications and are commonly used in power supplies.
14.
The rotating electromagnet induces a three-phase voltage ( Vg ) in the stator windings as if the machine were a synchronous generator.
15.
A rotary phase converter is a three-phase motor with special starting arrangements and power factor correction that produces balanced three-phase voltages.
16.
Further, the voltage transients due to the grid disturbances ( three-and two-phase voltage dips, especially ) will also be magnified.
17.
At this position, each secondary phase winding is short-circuited and no phase voltage is injected; consequently the speed is that of a normal induction motor.
18.
Phases with higher relative loading will experience reduced voltage, and phases with lower relative loading will experience elevated voltage, up to the phase-to-phase voltage.
19.
The single phase voltage is 110 V a . c . though having a " centre tapped Earth " reducing the voltage to Earth to 55 V a . c.
20.
"Spirit of Peoria " has no propellers or thrusters, and is powered by twin gensets, producing 700 kilowatts combined in 208 volt 3-phase voltage.
