Earthing Fault Level Data for Grid and Primary Sites

The earthing fault level dataset includes the three-phase and single-phase to earth fault levels for all Grid (132kV, 66kV, 33kV) and Primary (33kV, 20kV, 11kV, 6.6kV) substations based on the

UK Power Networks Long Term Development Statement (LTDS).

This data can be used in substation earthing system design and assessment. For further information on earthing refer to UK Power Networks' earthing standard EDS 06-0001 available from our website https://g81.ukpowernetworks.co.uk/. Please send any enquiries related to the dataset to [e-mail]

Methodological Approach

Fault level data is uploaded from UK Power Networks' data warehouse.
Site Functional Locations (FLOCs) are used to associate soil data to Key characteristics of active Grid and Primary sites — UK Power Networks

Quality Control Statement
Quality Control Measures include:

Verification steps to match features only with confirmed functional locations.
Manual review and correction of data inconsistencies.
Use of additional verification steps to ensure accuracy in the methodology.

Assurance Statement
The Open Data Team has checked to ensure data accuracy and consistency.
