GridOn, Israel
This projects aims were to develop and demonstrate a pre-saturated core fault current limiter device (PCFCL), to reduce the impact of faults on electricity distribution networks.
- Development and demonstration of a pre-saturated core fault current limiter
- Product design offers advantages of a non-superconducting pre-saturated core fault current limiter with instant response and recovery and a small footprint based on established transformer design and build process
- Commissioned into service in May 2013 at a UK Power Networks primary substation in Newhaven, where it has performed excellently.
Designed by GridON, this pre-saturated core fault current limiter uses a direct current coil to magnetically saturate the iron core, providing a very low impedance during normal operation and a high impedance in response to a network fault. It is based on combining industry standard proven transformer technology and GridON's concept of magnetic flux alteration to saturate the iron core.
The limiter is fully scalable for use at voltage levels on both distribution and transmission systems. Its design removes the need for superconducting components or associated cryogenic systems.
