Transformer Oil Purification
LH Marthinusen provides comprehensive transformer oil purification services to support insulation integrity, cooling efficiency and overall transformer performance. Effective oil maintenance plays a critical role in ensuring reliable operation and extending transformer service life across power and industrial applications.
Oil Analysis and Condition Assessment
Our services begin with detailed oil sampling and laboratory analysis to assess the condition of the insulating fluid. These assessments identify:
- Moisture content
- Dissolved gases
- Contaminants and impurities
This information supports informed maintenance decisions and structured intervention planning.
Oil Purification and Treatment Services
Oil purification processes are carried out to remove moisture and contaminants, restoring dielectric strength and improving insulation performance. Where required, complete oil replacement services are performed in accordance with defined project specifications.
Transformer vacuum treatment is conducted to remove trapped moisture and gases from both the oil and internal transformer components. Retro filling with FR3 ester oil is also available where an alternative insulating oil is specified.
