Description :

The transformer’s operating principle is based on Faraday’s law of electromagnetic induction. Electrical energy received by the primary circuit is converted into magnetic energy, generated flux flows through the closed magnetic circuit & the magnetic energy is reconverted into electrical energy in the secondary electrical circuit.
To attain the overall

What is Transformer ?


Transformer is a static electromagnetic conversion device. It transfers electrical power with one voltage ( step-up/step-down) from one electrical circuit to another separated electrical circuit with another voltage ( step-down/step-up).
The operating principal of transformer is based on Faraday’s Law of Electromagnetic Induction.

Title: 03 Phase Electrical Power is Constant !! Mathematical Proof ?

Published on 2020-12-16 15:08:33
image
Description :

Since the 3 phases ( both for voltage & current waveform ) are 120 degrees out of phase from each other, therefore 3 phase power is constant.

We can find it from mathematical proof that three-phase instantaneous power

Title: How many RPMs are needed to produce a current in a car alternator?

Published on 2020-12-11 14:46:08
Description :

Alternator rpm and temperature are two main factors that affect output current. Output current is directly proportional to alternator rpm.
Whatever the engine rpm, normally above 2000 rpm ( depends on drive/pully ratio ) of alternator speed is taken . If more rpm then more output

Title : How much power is needed to energize 11KV, 2500KVA Transformer?

Published on 2020-12-11 07:00:00
Description :

If someone is meaning no-load /fixed losses when energized a transformer, then It can be said that no-load losses are eddy current loss & hysteresis loss of the core.

How much power is needed depends on the following factors :

Eddy loss depends on frequency,
