KEMA high-power lab in Arnhem
ings can withstand a steady-state temperature of 200 degrees
Centigrade. The winding insulation is typical of the type used
in large rotating machines and considered most suitable for the
design of the distributed windings in it.
The most important feature of the pmFCL, emphasizes FaultCurrent, is its capability to prevent demagnetization of the ferrite
magnets during the flow of fault current by ensuring that peak
field values in the AC windings do not exceed coercive field
values in the vicinity of the magnets. Even in the unlikely event
of demagnetization of the permanent magnets, the pmFCL fails
safely by adopting its higher impedance state.
The KEMA High Power Laboratory in Arnhem is the world's largest independent testing and certification laboratory for medium,

high and ultra-high voltage transmission and distribution equipment. According to Bas Verhoeven, laboratory director, the
pmFCL performed closely with the FEM (finite element method)
magnetic design models. Having successfully completed its
range of testing, it was issued a Performance Certificate. The
pmFCL will be installed and network tested by a UK distribution
network operator later in the year and will be used in extending
the capacity of the power grid, said Verhoeven. "This development represents a new class of dry type fault current limiter with
low maintenance, running and installation costs, being both easy
to install and requiring no axillary power."
