However, increasingly, customers
are requiring this information as part
of a problem diagnosis or to verify
performance figures for a component
when its essential data has been lost. To
keep up with growing demand, Sulzer
has made a major investment at its Falkirk
Service Center that will enable the test-
bed load capacity to be doubled.
Until now, the Falkirk site has used a
1,250 kVA diesel generator that operates
through two step-up transformers to
provide 3.3 - 11 kV via high voltage
switchgear to the test cell.

This setup ensures a reliable power source

demand on the power grid. increase the load testing capacity to 2,000

The new investment by Sulzer will add a
2,000 kVA and a 700 kVA generator to the
site that will be synchronized through a
4000A LV switchboard, as well as a new
2,500 kVA transformer, that will double The majority of the equipment tested in

is now in place to allow multiple motors

The original capacity of the service center
was 1,000 kW in load testing, of which 800
kW could be used for testing vertically-
orientated motors, across a full range of
voltages from 400 V up to 11 kV at both 50
and 60 Hz.
