Transformer oil | Breakdown Analyzer

The ÖLPG Oil Tester is a portable “Breakdown Analyzer” for on-site testing of oils. With the ÖLPG Oil Tester, the breakdown voltage or dielectric strength of insulating oil is tested fully automatically and thus quickly and cost-effectively. A fundamental test of the oil quality of transformer oil is the breakdown voltage test. The following applies: The lower the resulting voltage, the worse the quality of the oil! The ultra-light transformer oil testers are impressive in their performance data and ideal for on-site oil testing. With the ÖLPG, plant operators are able to assess the quality of the insulating oil directly on site. If necessary, the appropriate measures would have to be initiated. The oil sample no longer needs to be sent to a test laboratory for analysis.

The procedure and a short shutdown time of less than five µs enable highly efficient testing. The high-contrast display of the testing device facilitates handling and navigation. With the Breakdown Analyzer synthetic oils, ester and silicone oils can be tested non-destructively. The breakdown voltage of insulating oils can be determined in a very simple way by taking the oil sample from the transformer or current transformer and subjecting it to the fully automatic oil test. The test result allows the operator of the equipment to assess the quality of the insulating oil and to decide whether the oil should be retained or replaced.

The automatically generated test reports can already be downloaded in PDF format to a USB stick! Due to the extremely fast voltage cut-off on breakdown, synthetic oils, ester and silicone oils can also be tested non-destructively! The pre-defined, fully automatic test sequences meet all current international norms and standards. The oil testing devices thus guarantee that the legal requirements for the prescribed oil tests are met.

In the coulometry of a titration solution, the determination of the concentration titer is not necessary, making it easier to operate than in volumetric titration. Many experienced analysts still feel the smell of pyridine in their nose with horror when they hear the name Karl Fischer. However, modern reagents and easy-to-operate analytical instruments cleaned up thoroughly with such ideas. Today, coulometric and volumetric Karl Fischer titrators allow practically all applications to be performed simply, quickly and accurately. Because of its selectivity and accuracy, Karl Fischer titration has become the most important method for water and moisture determination. With the KF-750, titration can also be followed “live” in the form of a measurement curve. At the touch of a button, it is possible to switch between classic and graphical display.

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.

Gas-in-Oil Analysis | TOGA-100-GC | Transformer Oil analysis

Gas-in-Oil Analysis | TOGA-100-GC – Gas-in-Oil Analysis (DGA – dissolved gases) has been successfully used for several years for the diagnosis and monitoring of oil transformers and tap-changers. DGA is considered one of the most powerful methods for assessing the condition of the transformer’s insulation system. Due to the natural ageing of the oil and the insulating materials, cracked gases are formed which are dissolved in the transformer oil. Especially under the influence of thermal or electrical faults. With the DGA analysis slowly developing faults can be detected. The temporal development of the gas concentrations allows a trend analysis.

By comparing the DGA results a characteristic fault gas pattern is determined. For the mobile DGA at the transformer on site, the TOGA 100-GC system delivers reliable and accurate measurements in a very short time. The gaseous decomposition products provide information about the type of fault in the transformer. The TOGA 100-GC system separates all eleven components of the gas to oil analysis in one injection. The TOGA 100-GC follows the ASTM 3612C method for gas analysis with headspace injection. For the laboratory gas chromatograph of the M-Labor series, there is also the option to connect an automatic sampler. The TOGA 100 Portable allows samples to be analyzed directly on site. A small helium tank is sufficient to operate the GC in the field. The column oven in each TOGA 100 GC guarantees a high sample throughput by fast heating and cooling.

The fully integrated TOGA GC systems are small, lightweight and, like all systems, modular. They can be easily upgraded and are easy to maintain. Sample information: This ASTM D3612 C method is used to analyze the eleven most common components.

Karl Fischer Titration | KF-700 | Transformer oil analysis

Karl Fischer Titration KF-700 | Determination of water content – The Karl Fischer Titration method for analytical water determination is considered the most important method for determining water content. Volumetric titration is the “classical” Karl Fischer titration.

The fundamental difference between volumetric and coulometric titration is the method used. One advantage of the volumetric method over the coulometric method is the lower effort required. The Karl Fischer volumetric titrator is more flexible when using solvents. The measuring range goes from 0.01 percent to 100 percent. For water content and water determination, the Karl Fischer method is used in the laboratory.. For all its advantages, manual titration is still established as the standard application in the laboratory. A piston burette with exchangeable dosing attachment is the first choice when perfection and flexibility are required. With regard to the aging process of transformer oil, the Karl Fischer Titration KF-700 is used. A special form of dosing is the “Preparing solutions” mode.

In this mode, a solvent is dosed up to the desired target concentration. A sample is weighed in, the volume added is calculated using a calculation formula and then added. This mode is suitable, for example, for the preparation of standards and solutions for viscometry. Important features: Automatic calculation of the addition volume without additional PC software. Dosing and filling speed can be optimally adapted to the dosing solution. Several methods with different parameters can be stored. Automatic transfer of the weight of a connected balance.

Usually, 10-15 user methods are sufficient for most needs.
