Why we convert KW to KVA when we install the distribution transformer in domestic , industrial and other locations. where we need required load rating and transformer rating .
But AC load are resistative , inductive and capacative so voltage and current are not in phase both have phase difference this phase difference define by the lagging and leading power factor. 
AC power is the product of voltage . Current and power factor and it unit is watt so we calculate the in KW and MW.


Calculation of KW to KVA

Kw = kilo×voltage×current×pf

Pf = power factor
And

KVA = kilo ×voltage × current

Now converting kw to kva
Kilo × voltage × current × pf =  kilo × voltage × current × pf

Kilo × voltage × current = ( kilo × voltage × current × pf ) / pf

KVA = ( kilo × voltage × current × pf ) / pf

KVA = KW/pf

Similar we can  convert KW to KVA

KW = KVA × pf

Example :- Convert the load  20 KW into KVA  and power factor is 0.8.

KVA = kW/pf

KVA = 20/0.8

KVA = 25

If 20 kW load then transformer required 25 KVA.

  1. IEEE Project Domain management in software engineering is distinct from traditional project deveopment in that software projects have a unique lifecycle process that requires multiple rounds of testing, updating, and faculty feedback. A IEEE Domain project Final Year Projects for CSE system development life cycle is essentially a phased project model that defines the organizational constraints of a large-scale systems project. The methods used in a IEEE DOmain Project systems development life cycle strategy Project Centers in Chennai For CSE provide clearly defined phases of work to plan, design, test, deploy, and maintain information systems.


    This is enough for me. I want to write software that anyone can use, and virtually everyone who has an internet connected device with a screen can use apps written in JavaScript. JavaScript Training in Chennai JavaScript was used for little more than mouse hover animations and little calculations to make static websites feel more interactive. Let’s assume 90% of all websites using JavaScript use it in a trivial way. That still leaves 150 million substantial JavaScript Training in Chennai JavaScript applications.
