Substation Applicable Standards.

Owaga_Jr

Hi Engineers,

For those in the design of substations, 6.6kV upto 400kV, what are the applicable international standards (IEC, EN, BS) that guides the designs of these stations, I am made to understand that IEC 61850 is more of the automation of the stations. However am looking at something that talks of the clearances, fault levels, type of breakers to use under different voltage levels, I have been majorly on the low voltage 415V and below, however I have found myself in a department where we are designing a 66kV AIS substation and I just wanted to get my facts right and not rely on the "I have seen it being done like this in all our prior designs".

Thanks in advance.

    I have attached National Grid standards in the UK which may guide you but not officially apply.

    For the avoidance of doubt, these are National Grid's company standards / specifications, and are not national standards.

    For 66kV you might also want to consider documents from the Electricity Networks Association, which (for the sake of this discussion) interpret the applicable standards in the light of GB/NI custom and practice and thereby comprise standards that DNOs adhere to (with their own company policies on top). On a private network you do not have to conform to all of them (but you will some, according to the connection agreement) but knowing what they are will give you a chance to make an informed decision.

    If I may ask, you have any links to the GB/NI standards you are referring to? Thanks in advance
