An earthing transformer is usually associated with three phase supply systems.
Earthing of any electrical system at the source is considered by most countries to be the safer practice with regard to personnel and equipment safety.
On a three phase system, the neutral would be earthed either directly or through some limiting impedance / resistance. When the neutral point is not available or does not exist with a delta secondary winding of the transformer, a neutral point needs to be created. This is the purpose of the earthing transformer, which could consist of a zig- zag winding, or a two winding star delta transformer where the star winding of correct voltage supplies an accessible neutral point when connected to the supply system.

∙ 15y agoIn North America (grounding ) Transformers is a code rule. It is to make a return path for a short circuit, to trip the overcurrent device protecting the transformer. Without a ground, the transformer winding is isolated and (floating), on a short to ground there could be no return path to the overcurrent device and the whole system the transformer is supplying could become enegrized up to the voltage potential of the transformer.

Where is the use of earth transformer?
It is used in where the transformer are connected in star delta.
How do you give earth ground in a rocky area?
1. USE GROUNDING TRANSFORMER OR ZIGZAG TRANSFORMER 2. USE SOIL CONDITIONING AGENTS - MARCONITE CONDUCTIVE AGGREGATE AND BENTONITE MOISTURE RETAINING CLAY ON EARTH ELECTRODE BACKFILL.
Explain the types of transformer and what are the uses of that?
Well there's the Decepticons who are bad guys, the use for them is the destruction of Earth, and the Autobots they are the good guys, the use for them is to stop the Decepticons from obliterating Earth.
Which type of transformer is use in gss?
Frgi transformer
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
What is transformer earth resistant value?
5
What is purpose of ten delta test on transformer?
To ascertain the life of insulation, or effectiveness of the insulation (HV to LV, HV to earth and LV to earth) of the transformer
Why the Yphase of the Voltage tranformer secondary is earthed?
When power is generated by the power company they use the earth as one of its wires. They use earth because the earth is a great conductor, therefore the end user can use this "wire" as another leg to their system. You can also do this with a delta transformer.
How do you earth in the 1600 kva transformer?
In 1600 kva transformer we provide NGR (Neutral grounding resistance)
Whether neutral grounding of generator transformer should be connected to grid earth mat?
yes it will have a local power uses then we can use it with separate earth pits and else cases i.e. if you are transforming power throgh Step up transformer then separete grounding transformer is required for NG. hope the above will clezar the doubts Regards K. Vithal
What is the use of ideal transformer?
Ideal transformer is useful in understanding the practical transformer..i does't have losses...
What is the application of pluse transformer?
why should we use pulse transformer rather than ordinary transformer
