Electronic transformers

Request for information – FOI13395

Thank you for your e-mail of 22 July 2013, requesting the following information from Ordnance Survey:

The detailed map of Brighton that I was requesting is concerning the positioning of electric transformers within the Brighton & Hove area and also about Earth Rods. If you have any information about such matters I would be grateful to receive them.

Ordnance Survey does hold the information you have requested and we attach the held information from our 'Data Capture Guide' in relation to such matters.

We are also able to provide to you the following 'advice and assistance' under section 16 of the Freedom of Information Act (FOIA) 2000 to assist you with your request.

In terms of 'transformers' we show these in our OS MasterMap® product data as Electricity Sub Stations (usually abbreviated to El Sub Sta or ESS as space permits). For a sub-station that is in a building we will capture the building subject to our minimum size for capture.

If there is just the equipment in a fenced area we do not capture the transforming equipment's position and will only capture the site perimeter and apply the appropriate descriptive text.

Please note, in some rural and mountain/moorland areas they may be shown on the map as a point symbol but will still be described.

We also capture much larger Electricity Distribution Sites that form part of the national distribution network rather than the sub-station sites that are more related to the domestic distribution of electricity.

We do not capture earth rods.

As all the requested information has been provided, we have determined that in all the circumstances of this case the Public interest consideration (section 17 FOIA) is not applicable in this instance.
