Draft Specification and Definition of
Dynamometer Test Generator
•
Assumptions
–
Test generator principally serves to support hydraulic
testing.
–
No custom generator designs, such as we have discussed in
the past will be included, i.e. high slip, low in-rush, special
environmental protections, or other considerations.
–
Selection of a catalogue IEC motor is acceptable, it will be
used as a generator*
* An approach used regularly in the wind energy industry
Catalogue Motor/Generator
Motor/Generator Available form ABB, Siemens, Loher, Leroy-Somer
