Transformer station | Transformer Insulation Oil Analysis

Insulating Oil Analysis | The most important criterion of an oil-filled transformer is an intact insulation oil, thus ensuring safe operation of the transformer. Why should one carry out the oil examination of a transformer? The aging process of the insulating oil is progressing due to strong stress and thermal influences. It is recommended to take an oil sample in case of the following events: Before commissioning a new oil transformer. For regular checks during operation. In all cases where there is a suspicion of damage to the oil transformer.

In case of malfunction or when the protective devices are triggered. When taking an oil sample, some factors must be taken into account. For a transformer insulating oil inspection, it is assumed that the oil samples are filled in suitable containers. An oil sample from electrical equipment tells a lot. The oil sample serves to document trends and tests. Impurities in the oil such as particles, acid number and viscosity etc. provide information about the condition of the oil. The aim is to determine changes due to aging and to detect functional defects at an early stage. If samples are taken improperly, the resulting measurement and analysis results are invalid. Insulating Oil Analysis.

Before taking the oil sample, it must be determined according to which standard the oil sample analysis is to be performed. The quantity and also the sampling point of the oil to be extracted depends on this standard. Periodic and chemical tests as well as chromatographic analyses (Gas-in-Oil and HPLC) of insulating oil are indispensable. In order to apply the entire spectrum of oil analysis in a targeted manner, WGM Support works closely with independent laboratories.
