Transformer - Distance From Wall

For storage??

Why would you want to store a wall?

It seems that transformer is made using gold, two walls of same rating is provided.

Refer TAC recommendation.

Refer the manufacturer

Are you asking clearances for a transforer installation?

It governs by the local regulation

You mean panchayat office or local electricity office??

I do not know whether your question is genuine or you are making fun on me ?

Of late I find many guests enter into forum and make fun on others.It should be noted that we (people like me ) wanted to share our knowledge and experience to others by answering their questions.

Another trend I have noticed is many posters simply do not bother to revert back after trying out solutions ,at their end ,especially for the problems being faced by them on operation of DG sets/Transformers/breakers/motors/relays/PLC etc.

However coming to your problem, in India every state has got an authority called "Chief Electrical inspedtor to government" (CEIG), who certifies every electrical HT installation and issues a safety certificate.They have stipulated certain norms on clearances as per indian electricity rules.You have to follow these rules.

Thanks for reply.I have not asked any fee for this.May be in other context I would have indicated a fee for certain services.You will agree with me for certain services we may have to spend man hours and our resources etc.

Dear Mr. saurabhpareek002,

I think you are in India and the IER defines various parameters from safety point of view and CEIG is the regulating authority who will inspect the electrical installation. If the instllation is in order, he will approve to energise the system, if any thing forund deviation, he will instruct to rectify and submit a compliance report.

How ever each country may have their own Rules and Regulations.

For general knowledge, pl refer here.
