FEATURE ARTICLE

virtually no operating overhead and that requires no maintenance
beyond simple inspection.
FaultCurrent has provided extensive design explanations in its
product literature. A cross-sectional view shows its three layers
of coils and ferrite magnets. Basically, it is constructed as a

three-phase 11kV device that comprises 8 dry insulated, copper
windings for each of the three phases wrapped around ferrite
magnets. There are 24 windings in total. The magnets are arranged in a patented octagonal fashion to comprise each phase.
The three phases are then placed on top of each other. The
copper windings can be connected in various series and parallel
combinations providing flexibility for creating different variants.
The overall dimensions of the unit are 3.5m x 3m x 3m. It weighs
57 tons in total, with the weight of the ceramic ferrite tiles accounting for 25 of the tons. It can act rapidly to increase its impedance in case of a fault, typically within less than 2 msec, and
can also reset very quickly following clearance of the fault, taking
less than a millisecond to do so.
The device is protected by external
cladding fitted with
several louvers
that allow for the
natural ventilation
and cooling. This is
considered sufficient
due to the dry type
winding insulation
using a combination
of high temperature Polyimide and
Glass Mica and the
strategic distribution
of the windings in its
structure. The wind-
