Historical data on motor insulation dissipation factor
Historical data on motor insulation dissipation factor
(OP)
Hi everyone,
I am looking for information and references on the possible correlation between motor life/reliability and Capacitance and Disspation Factor values. I am an EE and know about the meaning of C and DF but have never seen decent data showing clearly the value of this test (IEEE28) over time. Can anyone provide me help on this ? The question is about motors but relates to hydro and turbo generators as well.
With my best regards
Karim

RE: Historical data on motor insulation dissipation factor
Many thanks for your help. I happened to have joined Ontario Hydro when that TR 100185 report was being finalized. Great work and very informative data. They tested 4 or 5 motors under different conditions and looked at various test methods and how they correlated.
I wish I could access the other reports you mentioned but my company is not a member of EPRI.
The best for me would be of coure to have an example of maintenance data over the life of a motor that ended up failing in service !
Best regards
