LTDS Appendix 3 - Circuit Data

Our LTDS Appendix 3 dataset contains EHV circuit data from across Northern Powergrid's network. The naming convention for the circuit nodes is made up of the substation name, transformer number or busbar name. In some instances, abbreviations may be used on circuits where the node represents a circuit tee or set of isolators etc. All R, X and B impedance data detailed in this table are given as a percentage on 100 MVA base. The rating of each section is defined as either the continuous rating for cables or spring/autumn rating for overhead lines.

If you are unsure of any of the column meanings, please hover over the column heading for a description.
