NETWORK / 25 / JULY/AUGUST 2018 of the five foundations of the Government's modern Industrial Strategy, and 'place' can play a role in delivering positive out - comes from the energy revolu- tion. Novel energy approaches based around local areas can make good use of local conven- ing and planning powers in local authorities and enterprise partnerships. They can also help to drive local benefits such as high-value jobs associated with installation and maintenance of more distributed systems (jobs akin to the plumbing and heat - ing industry); lower costs for consumers to help alleviate fuel poverty; increased local dispos- able income; improved energy efficiency, helping achieve local authority ambitions; and reduced air pollution. This part of the Industrial Strat - egy Challenge Fund therefore aims to deliver four key objec- tives: l Prove investable, scalable lo- cal business models that; l Use intelligent, integrated approaches to deliver cleaner, cheaper energy services l Help develop more pros- perous and resilient com- munities l Benefit the national energy system as a whole. l Unlock a ten-fold increase in future investment in local integrated energy systems versus business as usual in the 2020s. l Create real world proving grounds to accelerate new products and services to full commercialisation l Build UK leadership in in- tegrated energy provision. These ambitious objectives will be delivered over the coming four years via a series of large scale demonstrators alongside development of future designs for local energy approaches. Be - tween them these will prove the most ground-breaking of today's local energy plans at scale in the real world and develop the next generation of detailed designs that form a pipeline of invest - able projects for the 2020s. Gaps in underpinning technologies will be targeted in an innova- tion accelerator programme. A research consortium will be funded to pull together knowl- edge from across the academic landscape. And lastly the Energy Systems Catapult will deliver a programme integration service which will provide capa - bility into projects and perhaps most importantly ensure insight from the programme on differ- ent types of energy model. At UK Research and Innova- tion, we are excited about this ambitious programme, but we cannot deliver it on our own. Its success will depend on the engagement of key stakeholders across the sector and beyond as we seek to accelerate our under- standing of the energy revolu- tion. That's where the industry come in.

"Traditional" Energy Innovation Approach A new approach… Technology Technology Service Service System System Business Model Business Model Jonathan Hopkins, sales director EMEA at S&C Electric Company, highlights the importance of locating faults on cable sections of both mixed and underground circuits. Traditionally, options for reclosing on mixed and underground circuits to locate faults have been limited. Mixed feeders are the most difficult to manage for reliability and protection, and they contribute highly to customer interruptions and customer minutes lost. They also are expensive to own and operate. Underground circuits have large numbers of customers, so utilities tend to prioritise repairing them for rapid restoration. As such, how faults are located is important. High fault currents on cable sections of both mixed and underground circuits create the potential for reclosing to damage the power system. The typical overcurrent-protection system for such feeder sections uses a one-shot-to-lockout ap- proach. Locating faults using this method is difficult, and the process involves thump- ing cables and trial-and-error switch-closing. Protection of overhead and underground circuits is handled differently. On over- head lines, reclosing is used regularly to manage transient faults. However, on under- ground cables, no auto-reclos- ing is performed because of the harm it can cause equip- ment. But the damage still can occur with human-initiated reclosing, which can be per- formed many times in search of each underground fault. PulseClosing Technology overcomes the equipment stress by using 95 per cent less energy than reclosing when lo- cating faults, preventing dam- age to the system. Whereas most technologies are for either overhead or under- ground protection, PulseClos- ing Technology is field-proven and applies equally to both, including mixed feeders.
