UK Power Networks (UKPN) has installed new technology which it claims can detect and protect electricity networks from faults faster than any similar technology currently available.
Dubbed to be the “world’s first and fastest”, the Power Electronic Fault Limiting Circuit Breaker, installed at a substation in Tower Hamlets as part of a trial, can detect faults on the network in just four-thousandths of a second – 20 times faster than existing ones.
It will also protect the network from any issues created by faults 250 times faster than a person can blink.
The device makes it easier for low carbon energy technologies such as wind, solar and combined heat and power (CHP) units to be connected to the grid and at lower cost by reducing the need for significant physical infrastructure upgrades.
Ian Cameron, head of innovation at UK Power Networks, said the project showed the business is driving change in the industry: “Through innovative technology, we are making it easier for a generation of environmentally-friendly, cost-efficient energy. Lowering the cost of connecting smaller-scale energy generation like CHP is a key component in providing a low carbon, secure and affordable future for London.”
The trial, which will continue until 2021, is part of a £6.2 million project funded by Ofgem’s Network Innovation Competition.
