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.

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 does an earth leakage transformer work?
What is the definition of earthing and how it works?
What is an Earthed voltage transformer?
An earthing transformer provides a neutral in a delta connected system.
What is the difference between chemical earthing and conventional earthing?
Chemical Earthing and Conventional Earthing are different types of earthing techniques. Conventional Earthing is based on plate earthing and pipe type earthing but Chemical Earthing on GI or Copper.
How do you use bentonite powder for electrical equipment earthing?
I want to use bentonite powder in place of salt and char coal for earthing of distribution Transformers and electrical lines
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 delta connected secondary?

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.

What is maximum distance of Earth pit for transformer neutral earthing?
100meter
What is an Earthed voltage transformer?
An earthing transformer provides a neutral in a delta connected system.
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.
What is the power line voltage between phase and earthing?
It is the same as phase to neutral. As the neutral is earthed at the electricity suppliers transformer.
How can we decide a transformer failed due to earthing problem?
Meggar test or continuity test of winding with respect to body / earth will tell you the truth.
Why only zigzag connection is used in earthing transformer rather than any other connections?
we need all zig-zag connections
