Revolutionary Ferrite-Magnet Fault Current Limiter Graduates from Testing and Heads to
Market; Eriez Magnetics Takes Major Position in the Developer, FaultCurrent Ltd in UK
at both 50Hz and 60Hz at KEMA Laboratories, a world-leader in
energy consulting, testing and certification, to confirm that our
pmFCL can be used on power grid across the world," he added.
"With the support of the UK government and our investors we
have been able to accelerate the completion of our development
program and are now working to appoint a network of global
sales representatives," said Ansell, who previously has held
executive positions with Alstom T&D, and GE. "We look forward
to sharing additional updates as we continue to work to bring our
state-of-the-art pmFCL to customers around the world."
Now the company is turning to the task of forging partnerships
with power system owners, system integrators and consultants
from across the world to help address the global issue of fault
currents and enable a smarter, flexible grid that can more easily
accept the connection of renewable & distributed generation.
FaultCurrent's product is considered an advanced Smart Grid
technology that provides additional fault level headroom when
needed during a fault event to quickly, safely and easily allow
the connection of new distributed generation sources. According
to the company, the technology behind this next generation FCL
has been achieved through a combination of magnetic engineering insights, including using low-cost ferrite permanent magnets
to saturate a network of inductors.
Unlike other fault current limiters, pmFCL is designed to be "fit
and forget" technology. The self-contained three phase unit is
delivered to the site as a complete unit that is ready to go once
placed on a concrete pad and requires no maintenance beyond
simple inspection.

FaultCurrent Limited, a UK-based developer of passive magnetic
fault current limiters, is reporting successful results from a recent
round of independent tests of its next generation fault current
limiter. With 25 tons of magnetic ferrite ceramic tiles at the core
of its novel design, it's a beast. It offers electrical utilities a new,
hassle-free way to assure connectivity to distributed generation
sources including renewable energy supplies.

Martin Ansell, CEO

"This is the final hurdle in a sevenyear journey that has involved
fundamental research, groundbreaking innovation, prototyping
and re-engineering resulting today
in a market ready product," said
Martin Ansell the company's chairman and CEO.

The final round of short circuit tests on the company's pmFCL
unit were conducted at DNV-GL Group's KEMA Laboratories
in the Netherlands and proved that its technology can be safely
applied to a power system to facilitate the rapid connection of
additional distributed generation power units including renewable
energy sources without an electrical utility having to incur the
costs, delays and the invasive risks of network reinforcement.
"We were able to test the short circuit (fault limiting) performance

It provides additional fault current headroom but unlike a current
limiting reactor, presenting a low impedance during normal 'in
service' current flows until an abnormal fault current instantaneously forces the device into a higher impedance state and
in doing so allows time for the power system's existing infrastructure the react to isolate the fault safely. Post-fault, the unit
instantly recovers ready to protect the network again. As a passive device, it incurs negligible operating costs and maintenance
while introducing minimal power losses - attributes prized by
utilities.
FaultCurrent was founded in
2012 as a business spin-out from
ground-breaking research undertaken by Dr. Jeremy Hall at the
Wolfson Centre for Magnetics at
Cardiff University. Hall also holds
a lectureship and research posiJeremy Hall, CTO
tion at Cardiff University's Wolfson
Centre for Magnetics where he
leads a team of graduate students working in the field of magnetic nanotubes, steel microstructures and composites.
The company's mission is to develop fault current limiting technologies that will extend the fault carrying capacity of an existing
power grid. Its research phase was completed in April 2013 with
