Analysis of windings insulation condition in high voltage machine stators
with use of Partial Discharge Method

30% of high-voltage machines failures is a result of degraded or damaged stator windings.

Non-invasive monitoring of stator insulation condition:

• does not require to interrupt normal machine operation,
• does not require to use high voltage for analysis ,
• does not require to know machine's history,
• does not require traditional off-line examination on halt.

The technique based on 15 years of experience:

• the research led in Robert Gordon University, Aberdeen sponsored by British Petroleum,

• the tests on real objects led by ELECO Electrical Projects, Aberdeen, ESL Ltd Aberdeen,

• widely used on drilling platforms on the North Sea on electrical machines of high importance in hazardous environment.

Handy, easy in use diagnostic system that allows:

• analysis under direct computer control,
• storing of the analysis results,
• scheduling repairs.
