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
Why neutral have zero voltage?
Your question should read, 'Why does a neutral have zero potential?' 'Voltage' means 'potential difference', and you cannot have a potential difference at a single point. A neutral doesn't necessarily have zero potential although it is connected to earth (ground). This is because the potential of earth isn't literally zero; it's just considered to be zero, in the same way that sea level is considered to be zero in terms of height. Furthermore, there is often a voltage drop between the neutral and earth -in which case, the potential of the neutral can be several volts higher than the potential of earth.
Can you use a three phase generator for a single phase machine?
yes we can by using one phase and neutral line
How do you wire a three phase four wire generator for single phase output?
In a three phase four wire system - voltage between any one phase and the neutral is single phase. Hence the single phase equipment or load between any one phase and the neutral.Another AnswerA single-phase load can be connected either between any line conductor and the neutral conductor, or between any pair of line conductors. The choice is dependent on the voltage rating of the load, which must match either the phase voltage (line-to-neutral) or line voltage (line-to-line) -these values will be indicated on the machine's nameplate.
Can the star point of a 400 volt three phase generator be grounded to produce 240 volts?
A 400/230-V three-phase generator hase three line terminals, together with a neutral terminal. The line voltage (i.e. the voltage between any pair of line terminals) is 400 V, while the phase voltage (i.e. the voltage between any line terminal and the neutral terminal) is 230 V.
Why is residential wiring called single phase if there are 2 phases coming in?
residential wiring are called single phase because the 2 phases coming in are one is neutral and the other is line.the neutral has a potential zero with ground and it is to provide a closed path for the current to flow through..the line is having a potential of 230V with the ground and a line together with a neutral is called a phase
Why voltage are not produce in netural wire?
First of all, by definition, 'voltage' is another word for 'potential difference', and a potential differenceexists between two different points. So a single conductor cannot experience a 'voltage' or 'potential difference'. Your question, therefore, should ask why a neutral conductor has no 'potential'. By general agreement, potentials are measured with respect to earth (ground), which is arbitrarily assumed to be at 0 volts.The answer is that a neutral conductor is earthed, or grounded, so theoretically its potential must be the same as earth -i.e. 0 volts. But, in practise, due to the resistance of the conductor that connects the neutral conductor to earth, the neutral conductor can often have a potential of several volts with respect to earth.
What is an AC single phase 2 wire system?
two wires coming off the secondary of the transformer ex. residential voltage of 120 volts each line, and one neutral wire, L1 to neutral is 120 volts, L2 to neutral is 120 volts, L1 to L2 is 240 volts.AnswerA single-phase, two-wire, system comprises a line conductor and a neutral conductor. In European countries, the line conductor for a residential supply is at a nominal potential of 230 V with respect to the neutral.In North America, a 'split phase' system is used for residential supplies; this is a single-phase, three-wire, system comprising two line conductors which and a neutral conductor. The nominal potential difference between the line conductor is 240 V, while the potential of each line conductor with respect to the neutral is 120 V.
What is the difference between a seperately excited DC generator and DC shunt generator?
The difference between a separately excited DC generator and a Shunt DC generator is that for a separately excited Dc generator , the excitation field winding is supplied by an external source different from that supplying the armature while for shunt generator, the excitation field windind is connected in series with the armature and supplied by a single source.
Does the moon have gravitational potential energy?
The gravitational potential energy doesn't actually reside in a single object, but in the relationship between two objects. Thus, there is a gravitational potential energy between Earth and Moon, or between a rock that you lift up on the Moon, and the Moon.The gravitational potential energy doesn't actually reside in a single object, but in the relationship between two objects.

Can you use phase voltage as a single phase?
A single phase supply can be obtained between any pair of line conductors or between a line conductor and a neutral conductor.
