Why doesn't the primary winding on a transformer have a neutral?
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
Diagram of star-delta connection of motor?
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.
What is the difference between star delta and wye 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.
Where can one find a neutral connection point?
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.
Why neutral is not requied in 3 phase?
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.
How can you how can you detect wye from delta with neutral connections?
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.
Is delta confiquation better than y?
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.
If good 1 is a neutral' what is its marginal rate of substitution for good 2?
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
Why neutral line is 230 v in three phase ac supply?
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.
What is the charge of water in a molecule?
It is net neutral but the oxygen carries a delta negative charge and the hydrogens delta positives so it is polar
Where do you ground a delta delta transformer?
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.
What would be the effect on the neutral bar of a 3 phase D B if the main incoming neutral is lost?
A three phase delta system does not use a neutral in its operation.

What is three wire grounded delta?
A three-wire grounded delta is a type of electrical power distribution system that uses a delta configuration with one corner of the delta connected to the ground. This setup provides a neutral point for grounding while maintaining the advantages of a delta system, such as improved voltage stability and reduced phase voltage imbalance. It is commonly used in industrial applications to supply three-phase power while ensuring safety and protecting equipment from faults. The grounded point helps to limit transient overvoltages and enhances system reliability.
How does an earthing transformer provide a neutral point for delta connected secondary?
There is normally no neutral point for a delta connection, Star or Y connections have grounded neutral points. So earthing transformers (or grounding transformers, GT, as they're called in this part of the world), are used to provide a neutral point in an otherwise ungrounded system. Typically they are found in utility transmission systems, where the grounding transformer provides a path for ground-fault current detection on the phases. The GT is connected in a zig-zag type arrangement such that positive-sequence (phase to phase) current is minimized, while zero-sequence (unbalanced) current presents a low-impedance path to ground. Usually, a reactor or resistor is inserted between the GT neutral connection and ground to limit the fault current to a level which will cause the detection to work but not damage the transmission equipment. See the links below for a simplified connection diagram and a somewhat more complex explanation.
