When phase and neutral will short means what will be the voltage in neutral?
If the phase and neutral wires are shorted together, the voltage in the neutral wire will be the same as the phase voltage. This is because the short circuit effectively bypasses any impedance or resistance in the circuit, causing the potential difference between the phase and neutral wires to be equal.
What is the equation for calculating the phase difference between two waves?
The equation for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
What is the formula for calculating the phase difference between two waves?
The formula for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
What happens when phase to phase line is connected?
If there is a voltage differential from phase to phase, and a conductance (inverse of resistance) between them, then current (amperes) flows. This is no different than phase to neutral, i.e. voltage across conductance generates current, (I = EC, or I = E/A) except that neutral current is zero in a true phase to phase connection.Note that phase angle is always relative. In phase to neutral, it is relative to (typically) neutral; while in phase to phase, it is relative to the other phase. By Fourier Analysis, the difference between two phases of the same frequency, but of different phase angles, is still a sine (or cosine) wave. Also, by Kirchoff's Current Law, (implied, and I will (sort of) not repeat it here), current entering from one phase and equally leaving via another phase will not reflect at all in the neutral conductor.The simple answer is that connecting phase to phase is a short circuit, just like connecting phase to neutral.CommentThere is no such thing as 'phase to phase' or 'phase to neutral'. The correct terms are 'line to line' and 'line to neutral'.
What is the difference between neutral point and earthing?
Earthing point is where conductor is directly connected to ground and its potential is always zero. Neutral is a return path in single phase system and in three phase system Neutral point will have zero potential if all the loads are balanced in the system. In un balanced three phase system even neutral point will have some potential
What is the power line voltage between phase and earthing?
It is the same as phase to neutral. As the neutral is earthed at the electricity suppliers transformer.
What is the relation between the path difference and phase difference?
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
What is difference between spn and tpn mcb db?
TPN MCB means Triple pole Neutral Miniature Circuit Breaker where as SPN MCB means single phase Neutral MCB.
Is there a difference between three phase and single phase electrical supplies?
Yes, there a difference between three phase and single phase electrical supply services.
What difference between using 4poles circuit breaker and using 3 single pole breakers?
3 pole would be for 3 phase, 4 pole would be 3 phase & neutral
Why cant take connection from phase line to neutral line?
A connection can be taken between phase lines, or between one phase and neutral. Both methods give a single-phase supply. Between phases the voltage is sqrt(3) times more than between one phase and neutral. In each case the load gives an unbalanced current on the 3-phase system but the idea is to average out the unbalances over a group of single-phase loads.
When 3 phase step down transformer primary side 2 phase came?
You cannot obtain a two-phase supply from a three-phase system. What you are referring to is a 'split-phase' single-phase system, in which one phase of the transformer's delta secondary is centre tapped, with that tap then being grounded and providing the neutral connection; the outer ends of the same winding provide two line ('hot') connections, L1 and L2. The potential difference between L1 and L2 is then 240 V, whereas the potential difference between either L1 or L2 and the neutral is 120 V.
