What happens if you connect live and neutral together?
It is the condition of the short circuit if the live wire directly comes to the neutral wire. If Normal wire burns, the circuit will break and everything will become normal except for that wire.
Why would a receptacle have power on both sides?
So, measuring the same voltage on both sides of what should be an active load means it’s an open circuit. The wire nut may have been loose, or one of the wires may not have been pushed in all the way, creating an open circuit.
When do you need a neutral wire in a transformer?
During balanced condition there will be no current flowing through the neutral line and hence there is no need of the neutral terminal. But when there will be unbalanced current flowing in the three phase circuit, neutral is having a vital role. It will take the unbalanced current through to the ground and protect the transformer or other equipment
Can a voltage transformer be used in an open circuit?
Current transformers are intended to be used as proportional current devices. Therefore a current transformers secondary winding should never be operated into an open circuit, just as a voltage transformer should never be operated into a short circuit.
Why is a neutral conductor considered a live conductor?
That is why neutral conductor is considered a live conductor, because there is current flowing causing voltage drop. Q8. Transposition in HT lines is not a means to get rid of neutral current and neutral conductor. Transposition is not there to cancel neutral current.
How is a current transformer different from a voltage transformer?
Current transformers reduce high voltage currents to a much lower value and provide a convenient way of safely monitoring the actual electrical current flowing in an AC transmission line using a standard ammeter. The principal of operation of a basic current transformer is slightly different from that of an ordinary voltage transformer.
