Lets compare between a star and delta connection in 3-phase power types. In a star connection, there are 6 connections (A1, B1 and C1 being the outer arms of the 3 armed star and at the centre, A2, B2 and C2). The center is called the neutral or star point which carries out the any unbalanced current loads through its connection. That is why if you lose out the neutral point in a star connection, there will be an overflow of current through to the loads. The loads also take in more current, generating much more power and could damage the appliance you are using and the components the line current is connected to, since excess heat and overworking may result.
In a delta connection, the connection has only 3 and on a piece of paper it is sketched as the connections being joined arm to arm. One side is A phase, B phase and C phase. Getting to the point, a Delta connection does not have a earth wire because the live voltage is always the same throughout the connection. Since phase and line voltage are the same and constants. It also means the line current will change without affecting other components within the circuit. Balanced Delta connected circuits or loads can only have their power supply sourced from a star connection and a balanced Star load can only have their voltage supply come from a delta connection.
Another AnswerWith a delta connection, the phasor sum of the three line currents is zero, whether the load is balanced or unbalanced, so no neutral is necessary.
What else can I help you with?
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.
How do you connect Wye connection to open delta connection?
Dont mess with transformers if u dont know how to read a wiring diagram It is easy if u know your relation to each of the phases and neutral and ground
What is a floating neutral wire?
a loose connection of a neutral wire
Can you make star delta connection with 2 contractors?
yes
What is the difference between a Y - delta starter and a star - delta starter?
No difference. Y is used as a symbol to indicate the star connection.

Why high voltage step down transformer uses delta as primary and wye connection as secondary?
because usually the step down transformers are used for supply so it requires neutral(return)path, we cant take neutral path through delta connection hence the star connection is used and mostly in step-down the star connection is used.
Differentiate star to delta connection of a transformer?
Star has one red, one yellow, one blue and neutral phases seperatelly. Delta has all four in sequence, combined.
Delta connection diagram?
delta connection current rating
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.
How can you terminate a 3 wire wye motor to a 3 phase delta connection?
To terminate a 3 wire wye motor to a 3 phase delta connection you need a 3 phase transformer to convert from delta to wye. Do not lift the common neutral connections inside the motor and rewire for delta, because the voltages will be wrong.
Why we get the 0 level in trans farmer when we use delta to star connection when you get the 220 volts at each terminals of star connection of transformer how we get 0 level or neutral equals to 0?
A: In the USA there is D delta connection or Y connection. The Y center point may not be zero if there is circulating current due to mismatch of the phases
How do you convert star delta connection to delta star connection?
hahahaa
Can delta connection be used on 3 phase 4 wire system?
A delta connected appliance can be connected to a 3-phase system by leaving the neutral unconnected. The appliance must be properly earthed.
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.
What is the reason motor runs delta connection?
Motor run delta connection because in delta connection it is less ampere needed and it sometimes it change the wye connection because of the available suply
When was Delta Connection - Kenya - created?
The delta connection was founded in 1984 this was one of the four main skyteam. Also delta connection was founded to have middle population community. Also known as feeder flights.
