Oil Sampling

The critical stage of any Oil Diagnostics

Sampling of the transformers correctly is vital to ensuring an accurate oil result, the result is only as good as the sample provided. There are several sampling methods used in the industry; it is recommended that the sampling procedure used is in accordance with the IEC 60567.

EA Technology has a number of highly trained Technical Engineers who visit client sites and take oil samples from oil filled assets. Whilst on site our Engineers carry out an onsite risk assessment to ensure all risk factors have been taken into account before sampling takes place.

All samples are taken using 500ml glass bottles with polycone caps to prevent gas escape. No sampling is permitted in plastic vessels for transformers.
