Electrical Notes Notes on Electrical Engineering: All Notes,Calculations & Abstracts are Based on Some Electrical References. All References are mention at end of each Notes. Dear Mr Parmar, You are one of the greatest, broad hearted and kind human being who believe in sharing the knowledge they possess as you will agree that the knowledge you have will be lost for ever when you leave this world.

It will enrich the knowledge of others interested in the subject and immensely benefit the mankind in its pursuit to excellence. I have come across with your articles while looking to solve one of my problems and I seek your wise advise in the matter. We have one tea manufacturing industry near Siliguri in the district of Darjeeling (West Bengal). We have taken up the task of efficient utilisation of electricity by looking into each and every factor affecting the electricity charges viz., contract demand, actual requirement, power factor, load factor, installation of required equipments, earthing, overall electrical wiring etc.etc., We have no idea about these and other factors affecting electric consumption. For this we need your guidance and like to know as to how you can help us or guide us in the matter. This is a business requirement and therefore, it will definitely be on cost basis. Waiting to hear from you, With regards, PK Goyal. Advanced reinforced concrete design by pc varghese pdf software.

Dear Jignesh parmar, I am working in 2MW Photovoltanic Solar power plant as Electrical Engineer (O&M), these plant generate power at day time & take power (Import) at night. At night Import power is used for plant lighting only as generation stopped after sunset, At the time of Import power, we have a light load (near about 10KW), due to which our power factor is Low.

& Electricity board charge panalty for low power factor. How can i improve power factor to 90-95%. Thanks & Regards, Leeladhar kashyap. Hi Jignesh Sir, I am one of the regular readers and followers of your website. I find this (your) site very knowledge enriching and insightful. On behalf of all the followers/viewers, I would like thank you for opening sharing your experience and expertise. Thank you once again. Pipe flow expert keygen download free.

Well, I would like to seek your advice/assistance on ‘How to calculate the electrical clearances of overhead electrical conductors of all voltage levels (415 volt, 6.6 kV, 11 kV, 33 kV, 66 kV, 132 kV, 220 kV, 400 kV, etc.)”. If there are any specific formulae, kindly share me.

I would be very grateful. Thrinley Bhutan +975-1760 9279. Jignesh I WANT TO INSTALL A SPD ON MY HOUSE BUT I AM GETTING CONFLICTING ADVICE. HOUSE IS IN THAILAND WITH LOTS OF ELECTRICAL ACTIVITY.

I HAVE A 50 KVA TRANSFORMER ON SITE SUPPLYING 3 PHASE POWER TO THE HOUSE. THE TRANSFORMER AND METER IS LOCATED ON A POLE ABOUT 60M FROM THE MAIN SWITCH BOARD IN THE HOUSE. LOCATION – SOME PEOPLE TELL ME TO LOCATE SPD ON THE POLE AND SOME SAY IN THE SWITCH BOARD. WHO IS CORRECT? SPD SIZE – SOME PEOPLE TELL ME TO GET A 4 POLE 20 KA DEVICE BUT OTHERS SAY 3 POLE 40 KA?

I HAVE SEEN 3 POLE, 3 POLE + N & 4 POLE. ALL COME 10, 20, 40, 60 & 100KA. WHICH IS THE CORRECT DEVICE FOR MY SITUATION I HAVE LOOKED ON THE WEBSITE BUT CAN’T SEE ANYTHING RE SPD FOR 3 PHASE CONDITIONS. CAN YOU PROVIDE SOME ADVICE RE THE ABOVE. Dear Sir, I have a question that, In EHV Network if the star point of source transformer is operating with solid/ resistance/ impedance grounding then is it necessary that any of the other receiving end transformers also required star point grounding in case of that receiving end transformer’s primary is star connected winding (The winding which is connected in the network).
