Can a wye transformer have a high leg?
Yes, a wye transformer can have a high leg, but it typically occurs in a specific configuration known as a "wild leg" or "high leg" delta system. In this setup, one phase is intentionally offset to provide a higher voltage relative to the neutral, often used in three-phase systems to supply single-phase loads. However, standard wye configurations do not inherently include a high leg; it is more commonly associated with delta systems.
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
What are the problems associated with the y-y three-phase transformer connection?
Your third leg is called the high leg and can exceed 180 or more volts. In a 3 phase panel you will loose a third of your circuits unless they are used for motors or other equipment that uses three phase evenly through its function {meaning it doesn't use one leg exclusively for controls or 110V functions. It get a bit involved explaining the windings of a transformer and center taps but suffice it to say one leg gets more than it's share of windings in the transformer. It was used in the early years of industry when single phase 240V systems were the only game in town and they wanted to get more power from the Wye set up prior to delta. It never was popular but a necessity for industry and grew only because of slow development incorporating the 208V delta 3 phase system.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
Why earthing transformer is zigzag connection?
A zigzag transformer is used in connection with 3 phase and is made up of 6 coils connected in a "Y" manner. Each leg of the "Y" is made up of a coil on a different phase leg of the transformer. The neutral formed by the zigzag connection is very stable. Therefore, this type of transformer, or in some cases an auto transformer, lends itself very well for establishing a neutral for an ungrounded 3 phase system. Many times this type of transformer or auto transformer, lends itself very well for establishing a neutral for an ungrounded 3 phase system. Many times this type of transformer or auto transformer will carry a fairly large rating, yet physically be relatively small. This particularly applies in connection with grounding applications. The reason for this small size in relation to the nameplate KVA rating is due to the fact that many types of grounding auto transformers are rated for 2 seconds. This is based on the time to operate an overcurrent protection device such as a breaker. Zigzag transformers used to be employed to enable size reductions in drive motor systems due to the stable wave form they present. Other means are now more common, such as 6 phase star.
How many relays in a transformer?
your grandmother's left synthetic leg . . . I HOPE THAT ANSWERED YOUR Question :) I'm glad i could help and be of your services
What is a half transformer and a half transformer?
a hole transformer
What is a tap changing transformer?
A transformer that has part of one winding partitioned in such a way that it can be removed or added to the winding. For example, you may have a transformer with 100 turns on the low side and 1000 turns on the high side. If it were a tap changing transformer on the high side winding, you may be able to add or subtract 100 turns, so the turns ratio can be anywhere from 9/1 to 10/1. <<>> This type of transformer is in common use in home distribution systems. On the side of the transformer there is a handle with the markings of 14,400/7200. By having this ability to work on two different primary voltages the utility only has to stock one transformer. The same transformer can be connected to the grid across phases at 14,400 or phase leg to ground at 7200 volts. The transformer ratios are so wound that the output voltage remains at 120/240.
