What should be the transformer to building separation distance for fire suppression?

Depends on size of transformer and type (dry,mineral oil, silicone) as well as ground slope and building construction.

What is the maximum capacity of 11kv transformer?

It depends on the design of the transformer but 1 MVA is a common size for an 11 kV / 415 v three-phase transformer.

Can you applied the voltage to neutral of the transformer?

The neutral of a transformer is usually grounded. Under this situation, this question is the same as asking whether you can apply a voltage to ground; the answer is yes, but I don't know why you'd want to. Sometimes transformer neutrals are insulated away from ground. If this is done, then you could inject "backwards" from the neutral up into the transformer. Again, I don't know why you would want to do this, though.

How do you size wire for a step down transformer?

You size it by the current required by the secondary, and the primary will be smaller wire.

How do you know that a 300KVA transformer is okay?

well it could be bad or good just be safe

What size ground wire for a 30 kva transformer?

The size of grounding wire is based on the amperage output of the transformer. The voltage of the transformer needs to be stated. Without this voltage a calculation can not be made. Amps = Watts/Volts = 30000/?.

Why is the neutral point grounded on a transformer?

The secondary side (output) of a three phase transformer develops a "separately derived system". That is why you do notsupply a neutral to a three phase transformer. It develops its own reference to ground by being bonded to the transformer casing and to a substantial earth ground, such as a ground rod. The XO tap on a transformer provides the neutral to the secondary line. It will have a double wire lug. The neutral wire going to the panel being supplied goes under one lug and the same size wire is to go to the ground lug on the transformer chassis The ground lug is also a double with the other lug to be wired to the earth ground.

What should be the transformer to building separation distance for fire suppression?

Depends on size of transformer and type (dry,mineral oil, silicone) as well as ground slope and building construction.

What is the footprint of the transformer foundation?

The footprint of a transformer foundation depends on the size and weight of the transformer, as well as the specific design requirements to support and securely hold the transformer in place. Typically, the foundation will be sized to provide adequate support and stability for the transformer, as well as to distribute the weight evenly across the ground to prevent sinking or shifting.

How transformer conduct current through ground?

A transformer doesn't 'conduct current through the ground'. However, in the event of a ground fault in the circuit supplied by a grounded transformer, the resulting fault current will flow through the earth back to the grounded terminal of that transformer's secondary winding.

What is the use of core transformer?

Why the transformer is kept at a height from the ground?

If you are referring to a pole-mounted distribution transformer, it's in order to maintain a safe clearance between its high-voltage connections and ground level.

What are the factors affect the magnitizing inrush current in power transformer?

1- residual flux existing before enegizing the transformer . 2- size of transformer . 3- size of power system. 4- type of magnetic material of the core. 5- the method of energizing the transformer.
