What Electricity Supply Solutions can do for you.

Transformer Oil Sampling

We offer a transformer oil analysis service to determine the quality of insulating oil.

Electricity supply solutions engineers have been trained in the strict routines needed to obtain a clean sample to BS 5263 Just like blood test provides a doctor with a wealth of information about the health of a patient, a sample of transformer oil, taken correctly, can tell service engineers a great deal about the condition of a transformer.

Oil is used to cool the transformer and to insulate internal component so it sees whats happening inside the transformer. So a laboratory analysis of a sample can provide advance warning of developing conditions such as tap changer burning or high moisture content.

The information from the oil analysis is only as good as the sample itself. service engineers have been trained in the strict routines needed to obtain a clean sample to BS 5263. These include: taking a sample while the transformer is at its normal working conditions the best way as what that oil is seeing during normal working conditions.

With sampling on a regular basis you can see the deterioration of the oil and pick ip vital information about the transformer. Typical tests carried out during the laboratory analysis of an oil sample include:

• Breakdown voltage (dielectric strength)
• Moisture content
• Dissolved gas analysis
• Oxidation
• Pcb
• Total conditioning analysis
• Plus many more
