Substation and Transformer Room - Design Guidance
|Publication Date:||1 April 2021|
This guidance applies, in general, to the majority of substations and transformer rooms on the System which might be described as of "standard" design. As such it is targeted at the major plant items in substations and transformer rooms.
It is recognised that this guidance will not cover all aspects of the design of substations and transformer rooms, nor many aspects of the design of "nonstandard" substations and transformer rooms (e.g. a transformer room with only a single transformer). Its intent is to provide the majority of answers to designers whose questions cannot be readily answered by reference to the relevant standards.
The expected users of this guidance are the designers of proposed reinforcements or other changes to substations and transformer rooms on the System as well as the designers of new substations or transformer rooms. These designers could be LU or its contractors or third party providers.
The purpose of this guidance is to support various LU standards to clarify the interconnection and operation of the major items of electrical equipment in a substation or transformer room.
