Grounding of 13.8 kV/440V/208 Transformer

Simply follow the appropriate electrical code in the country where the transformer is installed.

Thanks for very very prompt reply.

IT is quite clear from the question, the way it it is stated, is that it is in USA and further hint is NEC2010 does not say anything about it.

That is why this question is raised to the engg community where there may be somebody who has had a prior experience/ referral to provide me.

<...quite clear from the question, the way it it is stated, is that it is in USA...>

No, it isn't, and someone from, oh, pick a country, er, Malaysia could not be expected to know that.

It is inconceivable that a solution to the problem has not been previously established in the country of installation before. The original poster then has two options if the applicable local codes do not cover it:

1. Copy a similar installation elsewhere nearby.
2. Consult a qualified electrical engineer locally.

Sir,

The question was raised as I could not find a similar installation

2. Locally, guest is a qualified professional engineer but needs HELP.

Hence the request

Are you sure, NEC-2010 does exist?

-H.E

there is NEC2008 latest version

Since NEC2008 has no answer, I am still looking for an answer.Please help

have u googled it
