Thermal Power Plants – Transformer Care
Servicing and care unit for
prolonging the useful life of
oil-filled transformers and
reactors
• Continuous degassing,
dewatering and filtration of
the insulation oil
• Oxygen content, water
content and particulate
contamination in the
transformer are kept at a
constantly low level
• Increased breakdown
voltage of the insulating oil
and thus prolongation of
the service life of the
insulation
