How do you tell if a 220 volt circuit is single or triple phase?

Okay, engineer's turn: AC Power 101
120 Volt single-phase AC power is just that - you have one 'hot' leg and one neutral. Power is transmitted on the hot leg in a sinusoidal wave alternating (AC = alternating current) between positive and negative voltage 60 times / second (60 Hertz). The neutral provides the return path to complete the circuit back to the power generating point. (Don't do it, but you can disconnect the neutral lead from the plug, connect it to any good ground, and the device will work.) Now, 220 Volt 'single phase' really isn't single phase - it's two phase. You have two 'hot' legs and a neutral leg. The two hot legs each have the same sinusoidal wave form, but 180 degrees out of phase with each other. When one leg is at the peak of the wave, the other is at the bottom. If you measure between the two hot legs, you will have 220 VAC; between the hot and the neutral you will have 110 volts. Three-phase power has three legs carrying power, each with the same sinusoidal wave form, but 120 degrees out of phase with each other. When one leg is at the peak of the wave, another is 2/3 the way towards the bottom on its way down, and the third is 1/3 the way *up* from the bottom on its way up. In a generated 230 or 460 VAC 3 phase system, you should always measure about the same 230 or 460 volts between any two legs, (unless your supply power factor is way off).

How do you check single phase motor winding?
Single phase motor winding is often checked just by listening to the noise that the motor is making. An experienced person can tell if the motor is working at single phase or double phase.
Can anyone tell me how to build single phase variable frequency drive?
Single phase variable frequency drives are commercially available. Building it by an individual is complicated.
How do you determine a 3 phase motor and each winding?
To see if the motor is three phase or single phase look at the motor's nameplate. There it will tell you what the voltage needs to be and what system phase the motor needs to be connected to operate properly.
Can i run single phase dc motor from 3phase bldc controller. i m using single phase motor in motorcycle and controller from other electric vehicle. if yes please tell me how to connect it?
It is possible to run a DC motor on a 3-phase supply using a full-wave rectifier if the voltage is right.
My parents think my bisexuality is a phase how do I tell them it's not?
The best thing to do is to tell them it is not a phase and that they should support you. If they insist it is, which they will, tell them that even if it is a phase, I want you to support me and my decisions, now, here. Tell them not to wait until they are persuaded that your Bi to support you, they should support you now.
What motor gets more heated single phase or three phase?
Your question is a little like asking, 'How long is a piece of string?'! Do the two motors have the same power rating, or are they different?The rate at which energy is used by any machine is defined by its power rating. If the power ratings of two different machines are the same, then both machines use energy at the same rate. So if a single-phase motor has the same power rating as a three-phase motor, then they will both use exactly the same amount of energy over a given period of time.So, if a single-phase motor has a greater power rating than a three-phase motor, then the single-phase motor will the greater amount of energy in a given period. On the other hand, if a three-phase motor has a greater power rating than a single-phase motor, then the three-phase motor will the greater amount of energy in a given period.
Is a triple kiss weird to do?
I would tell you if i knew :]
How can i tell if it's simple duple or triple time?
I had the same problem. You can tell by counting.
How can you tell whether current is going into or out of a node in a circuit?
When you add up all the currents going into and out of a single node, you have to wind up with zero, or else you made a mistake adding them up.
Who will win at the bash orton or Triple H?
I think Triple H but you cant tell until the bash is over.
How do you tell if you have delta or wye power?
In Europe, low-voltage three-phase distribution is by means of a four-wire system (three line conductors and a neutral) supplied from a wye-connected transformer secondary. In North America, low-voltage is supplied from a delta-connected transformer secondary, one phase of which is centre-tapped and earthed (grounded). The single-phase supply to residences is then supplied by that particular phase, giving 240 V line-to-line and 120 V line-to-neutral. You can tell if you have a delta power when the phase voltage is equal to the line voltage and that you have a star power when the phase voltage =root 3(THE LINE VOLTAGE).
Does siries circuit have to have two bulb?
You need at least two components in your circuit before you can tell whether it's a series circuit or a parallel one.
