A mobile, trailer mounted Circuit Breaker (CB) has been developed and trialled in SSEN under a previous IFI project which has successfully proven the concept, but the methodology needs further development to ensure that it is fit for purpose. This project will develop a technical methodology utilising the installation of a 33kV pole mounted CB using live line techniques which can be used at all distribution voltages from 11kV to 33kV on poles with Air Break Switches.
Determine the technical and operational viability of the proposed methodology. Quantify the savings in CIs and CMLs which could be saved by the use of this technique. Determine the commercial viability of applying this methodology across the SSEN license areas.
