Transformer Oil Test:

Transformer oil is crucial in the cooling process of a transformer. Electrical and thermal stress or chemical contamination can cause failures and reduced component life. Our transformer oil testing services offer you a complete solution to your transformer testing needs. We provide you with fast analyses to IEC, ASTM, and ISO standards, helping you identify issues quickly.

Why choose transformer oil testing from SGS?
We can help you:

• Determine the basic electrical properties of transformer oil
• Identify if an oil is suitable for further use
• Detect whether filtration or regeneration is needed
• Enhance component life and reduce oil costs
• Maximize safety and prevent untimely failures
• Gain crucial historical data to understand changes or increases in key gases and the rate of gas production with our LIMS software
• Access your results fast – your data and analysis reports are available via our live web interface, so you can access your data at any time
