Find a focused route through sampling, oil properties, dissolved gas analysis and treatment. Use these guides to connect the diagnostic question with the detailed method and existing equipment pages.
Choose the question before the instrument.
Start with the sample and the laboratory scope.
02 / OIL QUALITYDielectric strength & oil propertiesConnect each measurement with the question it answers.
03 / DIAGNOSTICSDissolved gas analysis →Read the dedicated DGA guide and compare equipment.
04 / TREATMENTFiltration & purificationConnect treatment decisions with test evidence.
Start with a sample you can interpret.
Keep the asset identification, sampling record and agreed laboratory scope connected with the result.
Read the oil properties in context.
Breakdown voltage, moisture and dielectric loss describe different properties. Use the applicable asset documentation and approved procedure to define the test and its review criteria.
Follow the evidence behind the gas result.
Explore interpretation, chromatography and monitoring workflows in the dedicated sub-HUB. Keep the sample record, trend and wider asset evidence alongside the reported gas pattern.
Dissolved gas analysis: guides, interpretation and equipment →
Plan treatment around the condition question.
Define the reason for intervention and the verification needed after the work before comparing treatment systems.
Existing equipment guide
Connect the program with the laboratory setup.
Use these guides to organise the reading and compare equipment. Field work and acceptance decisions follow the applicable approved procedure and asset-specific criteria.
