There is phase to phase voltage in 3 phase system.AnswerYou don't get voltage 'phase-to-phase'; it's 'line-to-line'!
single phase, double phase & three phase
Phase monitors are used to detect single phasing, or loss of one phase of power from a three phase system. Most of the time they are used on very expensive motors such as high horsepower. They will shut down the starter, therefore shutting down the motor if all three phases are not available. One cause of this would be if there are three separate fuses protecting the motor and only one of them blows. The reason they are needed is because if you only send two phases to a three phase motor, it has a good chance of burning out the motor.
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
Burning a match is not a phase change. A phase change refers to a physical change in the state of matter, such as melting, freezing, vaporization, or condensation. When a match burns, it undergoes a chemical change as the reactants (matchstick and oxygen) are transformed into new substances (carbon dioxide, water vapor, and ash) through a combustion reaction. This chemical change involves the breaking and forming of chemical bonds, rather than a change in the state of matter.

if your ears are burning its suppost to mean someone was talking about you!! and if your palms itch its suppost to mean youre going to come into money...
The British focused attacking the Capitol by burning it and ransacking it.
Melting: change of phase, a physical phenomenon without change of the composition. Burning: a reaction of oxydation, a change of composition - a chemical change.
Yes, it is true that an average star spends about 90 percent of its life on the main sequence burning hydrogen into helium through nuclear fusion. This is the longest and most stable phase in a star's life cycle before it transitions into the next phase.
When burning camphor, you will observe a white flame and a distinct aromatic odor. Camphor sublimes, which means it transforms from a solid directly into a gas, without passing through a liquid phase.
Sublimation is a process similar to a burning candle but occurs at a lower temperature. It involves a substance transitioning directly from a solid to a gas without passing through the liquid phase.
The chemical reaction is:C3H8 + 5 O2 = # CO2 + 4 H2O
A three phase motor will not operate on single phase. The motor will run on two phases but will not start. Motors running on just two phases is called single phasing. The line current of the two legs will go high and it is this factor that the motor controller uses to trip the contactor to open the circuit and isolate the motor from the power source.
For the wax, yes. It changes to a liquid and then back to a solid. But some of the wax is also consumed in a chemical change as it oxidizes, along with the burning wick.
Burning wood does not involve sublimation. Sublimation changes a solid to a gas without altering it chemically. Wood burning does involve destructive distillation. The wood is chemically destroyed, and parts of it go off as gasses, which then combust.
