Unexpected HV or MV transformer
failure can be extremely costly, both
in terms of replacement and
production loss. OilData oil analysis
from EA Technology Analytical can
create a ‘health index”of
transformers, allowing more efficient
and cost-effective planning of
maintenance, refurbishment and
replacement.

Oil analysis provides detailed
information on the internal
condition of a transformer. Tests,
including oil quality, dissolved gas
analysis and furfuraldehyde levels,
offer insights into paper degradation,
abnormal electrical or thermal
activity and other effects of
transformer ageing.
