is essential to achieving a high
quality finish. The engineers
worked round the clock to
manufacture the new coils and
install them into the stator." After just 30 days the generator
was back on site, being craned
into position and reinstalled with
all the ancillary equipment, before
being put back into service.
Prior to the rebuild, the coils
were stress tested to earth in
accordance with EN60034-1, tan
delta tested and interturn tested
using EA Technical Specification
44-5 as the pass mark. Projects such as this have
highlighted Sulzer as a leading
provider of engineering solutions
to the power generation sector,
from on-going condition
monitoring to complete turnkey
projects. With a global network
of repair centers capable of
completing generator and turbine
repairs, Sulzer ensures it employs
experienced engineers, equipped
to complete projects on site if
necessary.
At the same time, the rotor
was refurbished and then
reassembled with the completed
stator before the final tests were
completed.
