Electrical books and guides
Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics and electromagnetism. Many companies and industry experts has been releasing technical books and guides in order to spread their knowledge, so they are all here, presented for you.
Introduction to energy generation
Prior to the discovery of Faraday’s Laws of electromagnetic discussion, electrical power was available from batteries with limited voltage and current levels. Although complicated in construction, D.C. generators were developed first to generate power in bulk.
However, due to limitation of the D.C. machine to generate voltage beyond few hundred volts, it was not economical to transmit large amount of power over a long distance. For a given amount of power, the current magnitude (I = P/V), hence section of the copper conductor will be large.
In later half of eighties, in nineteenth century, it was proposed to have a power system with 3-phase, 50 Hz A.C generation, transmission and distribution networks.
Once A.C. system was adopted, transmission of large power (MW) at higher transmission voltage become a reality by using transformers. Level of voltage could be changed virtually to any other desired level with transformers – which was hitherto impossible with D.C system.

Dear sir,
we have to make contact of switch upto 150A how to select the cross section area for rated current 150A
Thanks for the wonderful tips. We are into home appliance service and blogs like these are very helpful to us. Keep writing more.
Thank you so much for your efforts, this website is very useful
Is it possible to download all documents at once ?
Regards
This is the best web site ever for basics of electrical engineering!!
I have a 150 KVA generator. It suddenly developed a malfunction recently. When it is switched on, it runs for about 30 seconds and then goes off. It is electronically switched on or off.
Dear EE Portal,
Thanks for having such informative website.I am looking for quite long about Electricity metering sp[specifically define kwh meter, var and var hour meter and smart meter.
If their is any book regarding metering please send me on [email protected]
hello sir,
Please clear my confusion. While calculating load currents for sizing the cables, which P.F.should be used?? Old or new after compensation..? and also i heard that reduced cable size depends on the type of compensation.i.e. global, sector or individual…please explain.
Hello,
If you are talking about XLPE cables, then the power factor to be selected as per the load type. If it is residential, then you can go to 0.8 or below ; if it is commercial/ industrial you have to go to 0.9 or unity (If full motor/ pump loads).
You can select/ alter the PF as per the local authority approvals only.
For Fire pumps, large motors & AC units(with motor) always consider starting current as 1.5 times the normal load as standard to size the MCCB/ Isolator rating & then select the cable size accordingly.

plz upload any book for practical thinghs mean to say book only linked how to use thinghs pratically which enhance our innovation skills
I like working on electronics very much. And that is why I have chosen the field of computers and printers. Good post. Keep updating more.
Dear sir,
I always learning with EEP, the best site for electrical,
Sir I want to DOE fundamental of electrical science vol. 2 of 4, hear in site I just see vol. 1 of 4,
So please can you add in hear. ?
Can you please explain the function of Load Bank?
How can we size the Load Bank?
How can we upload a video on your this site?
hi,
thank you very much
hi,
can i get help you for the procedure.
Dear sir, I AM A REGULAR READER FOR THIS SITE. I AM A RETIRED ELEC ENGINEERING FROM .DEPt OF SPACE, ISRO IN INDIA.I AM SHARING THIS SITE CONTENT WITH MY FRIENDS IN ISRO.
IT IS WELL RECEIVED BY THEM & APPRECIATED BY THEM. AS SUCH I DO NOT HAVE A PAYPAL ACCOUNT. I AM INITIATING ONE &SHORTLY I WOULD LIKE TO MAKE A DONATION TO THE GOOD CAUSE FOR THE ELECTRICAL ENGINEERS (AND FOR THE SUBJECT) BY YOUR INITIATIVE . REGARDS.
