Oil Regeneration Solution for Life Time Extension
Challenge:
• Improvement of insulation condition
• Deceleration of ageing mechanisms
• Applied without interrupting transformer's operation
„ Mobile regeneration technology – SITRAM® REG
Potential Needs:
• Transformers with high aged oil
• Corrosive or potentially corrosive oils with corrosive sulphur
compounds (e.g. dibenzyl disulphide)
• Moderate aged and non inhibited oil
• Preventive maintenance strategy

Old Bushings could cause fatal Damage to Power
Transformers
Lifetime of power transformers on average is about 40-50 years!
Lifetime of condenser bushings on average is about 25-30 years!
70% of all bushing failures result in fire damage!
