The oil sampling set is used to take oil samples from electrical equipment such as transformers, converters or oil switches. When taking oil samples, make sure that the oil sample complies with the prescribed standard. A potential manipulation of the oil sample falsifies the analysis result. The big advantage of oil sampling with the Oil Sampling Set is that no outside air gets into the sample. The set ensures sampling according to the following standards: DIN EN 60567, IEC 567 and ASTM 3612, so the oil sample is ideally prepared for subsequent analysis in the laboratory. In order to avoid repairs and failures, the oil sample must be handled with care.

An early analysis of potential faults extends the service life of electrical equipment. Oil sampling is a crucial element in any oil analysis. Insulating oil analyses: These periodic tests are an important part of the maintenance of transformers for a safe energy supply. In the operational monitoring of oil-filled high-voltage equipment (transformers, instrument transformers, bushings, cables, etc..), decomposition gas analysis is becoming more and more a priority and an important part of the maintenance process. In case of electrical or thermal overload, decomposition gases are formed in the insulating oil, which can be analyzed.

Improper oil sampling or contamination of the test vessels can have a very large influence on the measured values of the individual test methods, so that completely wrong conclusions could be drawn about the quality of the insulating fluids. The oil syringes and aluminium containers must be rinsed with the liquid to be tested before taking the sample. Bottles made of brown glass or drawn aluminium are used as sample containers for insulating oils. Not only the sampling, but also the handling of the oil sample plays an important role.

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.
