Oil Sampling Set | OLEK | Transformer Oil analysis

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.

The Water-in-Oil ST-100 sensor is a temperature and humidity transmitter with a fast, reliable and accurate online transmitter for water activity in oil and temperature. The ST-100 is ideal for monitoring the humidity in oil or for online moisture measurement. The ST-100 is suitable for measuring humidity in lubricating, hydraulic or insulating oils, which is important for long-term performance and preventive maintenance of machinery and equipment. Oil moisture and water activity are automatically determined by the ST-100 Water-in-Oil Sensor.

The oil transmitter measures the water activity (also aw-value) and temperature (T). Both values can be read on the display. The humidity in oil can be given as absolute humidity in ppm or relative as water activity aw value. Our sensor measure the absolute water activity (aw) in oil and temperature (T) of the user oil continuously, reliably and accurately at all times. By integrating the measurement into the oil circuit, the measurement is carried out in real time and the reaction can also take place immediately. The risk of not detecting an increase in water activity (aw) between random measurements is eliminated.

The use of our sensors not only ensures that the quality but also guarantees safety extends the service life of the oil and minimizes downtime. The Water-in-Oil Sensor ST-100 is a robust online transmitter, which informs you reliably about a transformer failure. This is an accurate and cost-effective solution for online measurements of humidity in oil. Today’s oil sensors measure many parameters. With its robust housing and excellent performance, it is perfectly suited for integration into OEM applications.
