There is no neutral in a delta connection, because that is the definition of delta, a power configuration where current flows from phase hot to phase hot. The loads are A-B, B-C, and C-A.
Contrast this with star, where there is a neutral, and the loads are A-N, B-N, and C-N.
This only applies to three-phase motors. Because each phase of a three-phase motor is balanced, in the case of a wye-connected (star-connected) motor, the neutral current is zero (because the sum of three identical phase currents, displaced from each other by 120 degrees is zero), so there is no need for a neutral. In the case of a delta-connected (mesh-connected) motor, this situation doesn't arise, as there is no neutral current anyway.
neutral can only answer this question
In a three phase transformer, the primary winding is often configured in a Delta. The delta winding configuration does not use a neutral. The secondary winding is often in a Wye configuration, which does have a neutral. The Delta configuration is typically used for transmitting power to various locations, and thee phase loads where a neutral is not needed. The Wye configuration is typically used to distribute power in a facility where there are single phase loads that need a neutral. There are other reasons to use either Wye or Delta, such as grounding issues, but I think the short answer is probably what you're looking for (I hope). Hope this helps! Dave
Unfortunately, WikiAnswers does not support graphic images, so I will have to describe the connection in words. There are three windings, each with two wires. That is six connections. There are four connections in a star (wye) source, three hots and a neutral. The star connection has one end of all three windings connected (together) to neutral and the other ends connected to each hot. The delta connection has each winding connected end-to-end to each other in a ring, and each common point is connected to a hot. Neutral is not used in delta.
With a delta connection, picture a triangle. Each side of the triangle is a transformer or motor winding. Call the 3 corners of the triangle A, B, and C. There are only 3 wires except for a safety ground, which has no connection to, nor is any part of, the power transmission service lines.but for the star connection take our triangle above and use your wire cutters (literally) to cut the triangle apart at the corners. rearrange the three sides (transformer or motor windings) to form a Y. Where the three sides join in the centre, connect a fourth wire. Call this wire "neutral". Call the three ends A, B, and C. Connect the 3 supply service lines to A, B, and C.
A person can find a neutral connection point is testing the continuity of every neutral connection. This technique will enable a person to find a bad connection point.
As far as I understand, you don't need neutral line for connecting appliances that is 3-phase compilant. You only need the neutral line to connect a single phase appliance, which you connect along with one of the three lines.
The star connection has three phase terminal leads and one neutral lead. In case of delta connection it has got three phase terminal leads. the star connection is generally represented by Mercedes symbol with neutral line drawn from the mid point. The delta is represented like a triangle symbol with noneutral line shown.
In a Y configuration, all AC system loads are connected at the same one point and are typically unbalanced. A neutral cable is used where the three phases meet. The delta configuration uses three phases that are connected in a triangle without a neutral cable. The delta configuration is better when you need high voltage transmissions.
Answer is 0. Solution: MRS=delta(x2)/delta(x1) Good 1 is neutral it means that little change in delta(x2) makes infinity change in delta(x1). It means delta(x1)= infinity => MRS=0
3 phase supply can be configured in delta or Y. In delta configuration, think of the Greek letter delta (a triangle). The voltage is taken across two of the 'vertices' of the triangle. In Y configuration, the voltage is taken between a point and the 'neutral'. In a perfectly balanced system, no current would flow through the neutral line, but in the real world, no system is perfectly balanced. If you look at overhead power lines, the neutral line will be of a much smaller gauge wire than the 3 'hot' wires, because you can achieve close to a balanced load, therefore not much current will need to travel through the neutral.
It is net neutral but the oxygen carries a delta negative charge and the hydrogens delta positives so it is polar
In a delta-delta transformer, none of the actual conductors are grounded, directly or indirectly. You do, however, always ground the casing. This is protective earth ground, or PE ground, as opposed to neutral, which is grounded at the distribution panel, but which is a current carrying conductor. PE ground is not a current carrying conductor - it is a safety ground. Some texts use the term grounded conductor to refer to neutral, and grounding conductor to refer to PE ground. Simplest designation is neutral and ground. In summary, for a delta-delta transformer, there is no neutral, but there is always a ground. There is always a ground in any circuit, even when there is a neutral, and, except in a few special cases, those are two different connections.
A three phase delta system does not use a neutral in its operation.

The Ganga flows eastwards till Farakka in West Bengal. This is the northernmost point of the Ganga delta.
In a combined magnetic field, a neutral point is a place where the magnetic field is zero
