The output voltage between phases of ac 3 phase supply is 240V?
No, this voltage appears ACROSS individual phases, or BETWEEN a line conductor and the neutral
What voltage is found on a single phase motor?
Ac voltage
What is phase reversal in AC what are conditions for phase reversal in AC.?
I understand that when generating energy 3 Phases energy it is purposely generated at 90º phase lag. If one of the phases fails to lag and catches the other in frequency, the phases become same as one.

Will 3 phase AC motor stay running if you remove 1 phase?
Yes but it will not start. Usually if you lose one phase the current will go higher on the other phases and the motor overload protection will disconnect the motor from the supply voltage.
What is the 11kv phase to earth voltage?
6350.8 volts AC rms. The phase to earth voltage is ( square root(3) ) x lower than the phase-phase voltage on a 3 phase system.
Can you convert 1 phase to 3 phases?
You can buy a converter. Here is one example of many available on the web.Phase-A-Matic PAM-300HD Phase Converter, Static, 1-3 HPPhase Converter, Static, Input Voltage 208-242, Output Voltage 208-242, Input Phase AC 1, Output Phase AC 3, Input (Amps) 15, Output Amps 9.6 ...
Three phase voltage in india?
It is 230V single phase and 440V in 3 phase system at 50 Hz.AnswerIf the single-phase voltage is 230 V, then the three-phase voltage must be 400 V, not 440 V. The line voltage is 1.732 times the phase voltage.
What are the difference between single phase and three phase frequency converter?
A three phase converter, provides three outputs of AC current. The voltage peaks of each phase are stepped, so that they run at 120 degrees from each other. Three phases are used for large industrial motors and equipment, that need three phases to share the power on the cables. Single phase is just a two pole version of AC current, the same as comes out of your domestic sockets.
What is called an effective voltage in Alternating current and if you mention 115 V ac 3 phase means peak voltage is 115 or it is an effective voltage?
115 is the RMS voltage. The actual voltage is a sine wave from -167 to +167 relative to ground. RMS stands for root-mean-square, and it a way of saying that 155 Volts of DC would do the same work on the same sized load. There can be up to 3 phases, and they are the sine wave, shifted by a part of the curve. In most houses, there are 2 phases, and the voltage to ground for each is 110 to 120 V RMS. The voltage between the 2 is 230-240VRMS. 3 phase gets very complex. Each phase is 115 to ground or neutral. 3 PHASE 115V AC EACH PHASE IS 120 DEGRES PHASE SHIFTED THE EFFECTIVE VALUE IS .639 X 115 THE PEAK VALUE OF PHASE IS 1.41X RMS VALUE.
What is current and voltage waveforms are in phase?
If current and voltage of an AC are in phase, then the "power factor" is 100%, and the load is a pure resistance, with no inductive or capacitive reactance (at least at the operating frequency of the AC).
How many phases are in ac electric?
A.C. is generated, transmitted, and distributed as three phase.
