What types names of windings does the transformer have?
The primary winding is connected to the supply. The secondary winding is connected to the load. A tertiary winding (if used) is a third winding, which may be connected in various ways.If the transformer is a three-phase transformer, then there are three common configurations: wye (also known as 'star'), delta (also known as 'mesh'), and zig-zag.
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 will happen if induction motor is in star-star connected?
If a motor is connected in a star configuration it will operate at a slower speed. This is the working process that a star delta starter operates on. At first through the starter the motor starts in the star connection. When the motor gets up to its highest speed in that connection it times a timer out , the star starter drops out and the delta starter pulls in and then connects the motor in the delta connection. This allows more voltage to be applied to the motor and it then speeds up to its nameplate rated RPM.
How do you wire a 12 lead motor in star delta?
This is a 3-phase, dual-voltage motor. The 12 leads represent six different windings. For the higher voltage, pairs of windings are connected in series, then the three resulting pairs are connected into a delta configuration to tie to the power source. For the lower voltage, the pairs of windings are instead connected in parallel before combining them into the delta configuration. The windings MUST be combined in the proper order AND in the correct phase for it to work. Mistakes result in great quantities of smoke being released! Each of the leads should have a label, such as T1, T2, T3, etc. It will be either an adhesive label or sometimes printed in ink right on the wire. There is no standard labeling scheme, so each manufacturer always shows the connections for each voltage on the motor nameplate. There is no real way to guess at this, if the nameplate is missing contact the manufacturer for a diagram.
How many windings are in universal motor?
one windingAnswerA three-phase motor has three phase windings, normally (but not necessarily) connected in delta.
Is 3 phase star transformer has more winding than delta?
The # of windings in a transformer are based on the primary and secondary voltages the transformer is rated for not the way the windings are connected.

Is a step up transformer a Ynd or a Dyn?
Whether a transformer is 'step up' or 'step down' has nothing to do with the way its windings are connected, so it could be wye-delta or delta-wye.
How does a star winding shifts to a delta winding in a three phase motor?
To shift from a star winding to a delta winding in a three-phase motor, the connections between the windings need to be rearranged. In a star winding, the ends of the windings are connected to a common point (neutral), while in a delta winding, each winding end is connected to the start of the next winding. By physically switching the connections, the motor can be reconfigured from star to delta winding.
What is The Connection in three phase transformer?
the connection here meant for the connection of windings in three core or limbs of a transformer. it might be delta or star connected.

What is the difference between a Delta-connected and a Y-connected transformer?
With three windings, you have six terminals. Call them A1, A2, B1, B2, C1, and C2, representing phase A, B, and C. In the delta configuration, A1 is connected to C2, C1 is connected to B2, and B1 is connected to A2. Power is from phase to phase - A1C2, C1B2, and B1A2. In the wye configuration, A2, B2, and C2 are connected together, and are usually connected to neutral. Power is from phase to neutral - A1, B1, and C1.

Are motor and AC DRIVE V F D is connected in delta?
Yes, a motor can be connected in a delta configuration when using an AC drive with a Variable Frequency Drive (VFD). In delta connection, the motor windings are connected in a way that allows for higher voltage applications, which can enhance performance and efficiency. However, the specific configuration depends on the motor's design and the requirements of the application, so it's essential to ensure compatibility with the VFD settings. Always refer to the manufacturer's guidelines for the correct wiring and configuration.
Give details about star and delta connections as much as you can?
Star (Y) and Delta (Δ) connections are two configurations used in three-phase electrical systems. In a Star connection, one end of each of the three windings is connected to a common point (the neutral), while the other ends are connected to the phase lines, providing a higher voltage across the load. In contrast, the Delta connection links the windings in a closed loop, allowing for a higher current capacity and providing more power to the load. Star connections are typically used for lighter loads and in starting motors, while Delta connections are preferred for running motors and heavy loads due to their efficiency in power delivery.
