Single or Three phase Ac Circuit?

Both are possible. Single phase requires a neutral (or two phases, such as "Single-phase 240 V) to return the un-used voltage on the "down side" of the generating cycle. Three phases equal "each other out" on the up and down side. One phase generating positively while the other two are at various points of positive and negative on the sine wave to balance each other out.


What is a cosine signal in detail?

A sine signal, shifted 90 degrees in Phase. It otherwise is practically the same. Also, when a cosine signal coexists with a sine signal, it can be on the same frequency without interfering. The consequence of that is ... Two Channels can exist on the same frequency which are the Sine and the Cosine, and they can be separated in a receiver that can process and separate both of those Phases.


Is 208v 3ph the same as 220 1ph?

No, not at all. Single phase power consists of two "hot" conductors whose sine waves are 180 degrees apart. Three phase power has three "hot" conductors whose sine waves are 120 degrees apart. The voltage level has nothing to do with it.


What is meant by single line diagram?

Single sine diagram is graphical representation of electrical circuit drawn using single line instead of drawing 3 separate lines for three phases.


Sine wave can be split into?

a)set of sine waves b)set of sine waves with phase zero


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.


How many degrees are the current and voltage out of phase with each other in a pure resistive circuit?

The voltage and current sine waves cross the zero line at the same time and going in the same direction. The phase angle is 0°. They are said to be in-phase.


How to Construct a single to threephase inverter?

Very complicated, first you have to rectify your single phase to get DC then you need a 3 phase sine wave signal, that can be generated with a MCU, to drive three pairs of push pull amplifiers that is connected to a three phase transformer's primary windings and you have your output at the secondary


What will be the output of differentiator if the input is sine wave?

a phase shifted sine wave of a different amplitude.


What is the meaning of phased out?

The simple definition of out of phase is a condition where two alternating voltages do not have peaks and troughs occurring at the same instant. If we consider the sine wave of the AC power grid, the voltage varies with time, and it traces a sine wave on a graph or oscilloscope. It has positive and negative peaks, and if another AC sine wave (of the same frequency and amplitude) is compared to it, we can check the phase difference. If we use a oscilloscope, which is basically an electronic graphing machine, we can put the two signals in on different channels and see both simultaneously. When we comepare them by overlaying them, if both waves appear as one, they are in phase. Positive and negative peaks will be happening in each wave at the same instant, and just a single sine wave will appear on the scope display. If any phase shift is present, the other wave will be visible. Both waves will appear and can be distinguished. There are a number of different applications where phase shift is a critical consideration. Phase differences must be taken into account when bringing generators online, to cite one example. Significant differences in phase can cause tremendous damage to equipment that is paralleled (connected) at the wrong time.


What is out of phase?

Out of phase means that the sinusoidal waveform of voltage and/or current is not exactly in step with the reference phase. Expressed mathematically, it means that the coefficient of the sine function for one parameter is not the same as the other parameter. One may be x, and the other may be x+120. (This is an example of two phases in a three phase power system.) Another example might be where voltage is x, and current is x-23. This would be a case of a power factor of 0.92, such as for a typical large induction motor with a reactive phase angle of 23 degrees.


What is phase of a sine wave?

The phase angle varies from 0 to 360 degrees as the wave cycles.
