The Importance of Neutral Wire in 3-Phase Systems
Due to the Earth’s ground connection, the neutral wire will not supply energy if it touches a grounded object – no spark will occur, and no current will travel. The difference between neutral and ground is addressed in other articles, but an interesting note remains.

Why do 3 phase induction motors not need a neutral? – Electrical Volt
11 févr. 2022In the case of 3 phase induction motor, the neutral current is zero. This is the reason why the induction motor star point is not grounded. Under the above condition, no current at any instant will flow in a neutral conductor. To understand it let’s take the three-phase waveform and instantaneous current at any instant.

why 3 phase has no neutral – Wiring Work
13 mai 2022The total power output of the three-phase system is the sum of the individual phase outputs. This is why a three-phase system does not require a neutral wire. Since the three phases are already in balance, none of the phases requires a neutral connection to ground. A neutral wire is only when a single- system is used, as the …

electrical – Why Do 240V Circuits Not Require Neutral? – Home …
short answer: it’s because the two, 180 degrees out of phase, feed wires essentially take turns being the return wire every time the phase switches. 240V is the difference between them, and so when leg 1 is at +120V the other leg is at -120V and power is flowing from leg 1 to leg 2, but half a cycle later they are swapped and the power is flowin…

Role of the neutral conductor in three phase systems
The connection between neutral and earth allows any phase-to-earth fault to develop enough current flow to trip the circuit overcurrent protection device. wikipedia source. On a three phase system you can have a neutral wire but it is optional. Below are two three phase load configurations, Delta and Y.

Definitions Ground or earth in a mains ( AC power) electrical wiring system is a conductor that provides a low- impedance path to the earth to prevent hazardous voltages from appearing on equipment (high voltage spikes). [citation needed]

when does the neutral wire in a 3 phase system carry voltage?
Thus, imbalance 3 phase system will have neutral current and the proportional voltage drop along the wire. In the real world, there is no perfectly balanced 3 phase system. That is why most of the time when neutral voltage is measured against the local earth, there will be a voltage, mostly around 6 volts for the 415 volt systems.

Why ship power distribution systems have no neutral?
Neutral is not required to pass 3-phase delta power. On land normally high tension lines are delta only. On ships and planes many use 400HZ 3-phase delta. If source and destination transformers are delta, then balance to Earth or floating ground is not needed. It saves 1 extra wire. That’s the short answer. – user105652 Mar 10, 2019 at 20:36

A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line-to-ground voltage because it uses less conductor material to transmit a given amount of electrical power. [3] lesoutrali bot
