Temporary power and temperature
control solutions specialist, Aggreko,
has provided power for
First Hydro to test a
newly manufactured
generator stator (the
stationary part of the
generator that houses
the rotor) at the
Ffestiniog plant in the
Snowdonia region of
Wales.

Aggreko used three 1250kVA
diesel generators, working in
synchronisation, to set up the test
rig, taking just a day for installation
and half a day for decommissioning.

The generators were set up to
produce very low voltage that was
run through a transformer
to step up the power to
3.3kV. This was then
connected to a cable
which had been coiled
around the stator bore to
produce a magnetic field,
thus simulating the
conditions of the powergenerating
process.
