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 many earthing pits are required for 3 phase 7.5 kva GEN-SET?
one
Earthing required for machine operating on 2phase?
Do you REALLY mean a 'two-phase' system? Two-phase systems are archaic, and haven't been used for many decades.
How many types of earthing methods are there?
There are at least six types of earthing system, identified as follows:TNTN-CTN-STN-C-STTITThe first letter indicates the type of earthing at the distribution transformer, with T (= 'terre') indicating that one or more points of the supply are directly or 'solidly' earthed (e.g. an earthed neutral), and I indicating that either there is no earth at all, or earthing is achieved via an impedance.The second letter indicates the earthing arrangement at the electrical installation, with N indicating that all conductive parts are connected to an earth terminal provided by the utility company, and T indicating that the conductive parts are connected directly to a buried earth electrode.The third letter indicates the arrangement for the earthed supply conductor, with C indicating that the supply's neutral and earthing conductors are combined, and Sindicating that the supply's neutral and earthing conductors are separate all the way from the transformer.The fourth letter, S, indicates that within the installation, the neutral and earth conductors are separate.(The TN-C-S system is also commonly known as 'protective multiple earthing'.)
Transformer with many output terminals?
Your question is incomplete -- what about the transformer?
What is the ampere range value of transformer?
This typically has to do with how many amps you can safely pull from the secondary of the transformer.

A transformer can only?
A transformer does many things.
What type of software is required to install Flash Slideshow?
The type of software required to install Flash Slideshow would depend on what version of Flash Slideshow is desired by the individual. There are versions compatable with many different systems.

How many wires are input in a berry-type transformer?
1 wire is input in this type of 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.
What tools are needed to install Dorema Awnings?
There are many tools that are required to install Dorema Awnings. One would need a tape measure, level, a ladder, a drill, sockets and a ratchet, and eye protection.
