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 earthing are required to install transformer?
Four number earthing are essential for installation of transformer as under : 1) Two earthing for transformer body. 2) Two earthing for Neutral Point. Note : Numbers of earthing may be increase as per the client requirement.
How do you connect an earthing transformer with star connected secondary?
transformers transform
What is maximum distance of Earth pit for transformer neutral earthing?
100meter

What is the difference between earthing boss and earthing lug and where to use?
An earthing boss and earthing lug are parts of a grounding connection. An earthing boss is in a casting that allows for the drilling and tapping of hole. A earthing lug is used to bond a wire to the ground.
Why only zigzag connection is used in earthing transformer rather than any other connections?
we need all zig-zag connections

How do you connect an earthing transformer with delta connected secondary?
You have to connect each phase (R,Y & B respectively) of earthing transformer zig zag winding to each phase of power transformer delta secondary respectively. Then the zig zag winding of earthing transformer star point to be earthed.
How do you install earthing neutral for transformer in transformer room?
you shouldn't do it yourself, get an electrician.
Is the star-delta transformer commissioned without earthing transformer or NGR?
Yes, possible. NGR or earthing transformers are used when it is necessary to limit the fault current.
How does an earth leakage transformer work?
What is the definition of earthing and how it works?

Why earthing is use in transformer?
Earthing of a transformer is done to 1:reduce the sensitivity of protective relays. 2:reduce the damage due to fault current. 3:get rid of great loss of equipment and money in case of any earth fault.
