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
