Why Transformer Rating In kVA, Not in KW?In Simple words,
There are two type of losses in a transformer:
1. Copper Losses2. Iron Losses or Core Losses or Insulation LossesCopper losses ( I²R)depends on Current which passing through transformer winding while Iron Losses or Core Losses or Insulation Losses depends on Voltage.
That’s why the Transformer Rating may be expressed in...

Introduction to Electrical Transformer

Introduction to Electrical Transformer
What is a Transformer?
In Very Simple words.
Transformer is a device which:
Transfer Electrical power from one electrical circuit to another Electrical circuit.
It’s working without changing the frequency.
Work through on electric induction.
When, both circuits...
Why we are use 11KV / 22KV / 33KV / 66KV / 110KV / 230KV / 440KV this type of ratio?
Why
we are use 11KV / 22KV / 33KV / 66KV / 110KV / 230KV / 440KV this type
of ratio. Why can’t we use other voltage ratio like 54KV / 99KV etc?
When an alternator generates voltage, we always use a multiple of 1.11 because for a pure sine wave the FORM FACTOR
is the ratio of rms value...
How to choose transformer rating?

How to choose transformer rating?
When an installation is to be supplied directly from a MV/LV transformer
and the maximum apparent-power loading of the installation has been
determined, a suitable rating for the transformer can be decided, taking
into account the following considerations:
The...
Working principle of Transformer

Transformer
Working principle of Transformer
Transformer works on the principle of mutual induction of two coils or Faraday Law’s Of Electromagnetic induction.
When current in the primary coil is changed the flux linked to the
secondary coil also changes. Consequently an EMF is induced in the...
