UKPN trials new tech to drive a greener electricity grid

The circuit breakers help to easily add low carbon technologies like wind, solar and combined heat and power to the grid at lower cost

New technology that is expected to make it “easier and cheaper” for low carbon energy sources to be connected to the grid is being trialled by UK Power Networks (UKPN).

The distribution network operator has installed what it claims is the “world’s first and fastest” Power Electronic Fault Limiting Circuit Breaker device at a substation in Tower Hamlets.

It says the technology can detect and protect the electricity network from faults in just four-thousandth of a second – 20 times faster than any existing circuit breakers.
