GridON’s 30MVA Fault Current Limiter successfully completed short-circuit testing and was shipped to Western Power Distribution. GridON Ltd was awarded a contract for its novel fault current limiter (FCL) by Western Power Distribution (WPD), the electricity distribution network operator for the Midlands, South West and Wales.

Following a contract signature in February 2014, GridON completed the design and build of a 30MVA FCL in July 2014. The device has undergone a complete factory type test, as well as short-circuit testing under rigorous conditions at Ausgrid Testing & Certification lab. During the tests, the FCL limited 20.2kA first-peak fault current by over 50% and withstood 13.1kA rms (33.4kA peak) prospective fault current for 3 seconds. WPD approved the successful testing and the product is currently in transit to a primary substation in Birmingham for installation onto the live network.
