Power for testing

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.
