The Importance of Transformer Oil in Performance
Transformer oil analysis plays a critical role in maintaining the efficiency of electrical equipment. Mineral oil is the most widely used transformer oil due to its excellent insulating and cooling properties. It transfers heat to the transformer housing through convection, ensuring smooth operation and preventing overheating. By filling internal spaces effectively, mineral oil boosts performance and prolongs the transformer’s lifespan. Oil-filled transformers benefit from better heat dissipation and reliable operation. Regular oil testing preserves these advantages. Technicians perform transformer oil analysis to gather essential insights about the transformer’s internal condition. Routine sampling and testing protect oil quality, ensuring long-term efficiency and reliability.
Detecting Issues Through Advanced Oil Analysis
Dissolved degradation and decomposition products in transformer oil signal weak points within the system. These by-products indicate wear, internal damage, or faults. Standard oil quality checks often miss these issues, so advanced methods become essential. Gas-in-Oil Analysis plays a crucial role in identifying these problems. This testing method tracks the oil’s aging process and highlights potential issues early. Laboratory analysis breaks the oil into its smallest components, providing insights similar to a blood test in human health. These results allow technicians to detect contamination or early signs of wear.
Standards and Proper Procedures for Accurate Testing
The DIN EN 60422 standard outlines proper guidelines for transformer oil analysis. Following these guidelines ensures accurate and consistent results. Correct sampling techniques prevent contamination and protect the validity of the analysis. Adhering to these procedures helps uncover potential issues early. Regular testing improves transformer reliability, protects system performance, and ensures that transformers operate efficiently throughout their lifespan.

Karl Fischer Water Content | KF-700 | Determination of water content
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.

Corrosive Sulphur | CS100 | Corrosive Sulphur Kit
The CS100 Corrosive Sulphur Kit provides a practical and cost-effective alternative to expensive laboratory tests. Its purpose is to detect corrosive copper sulphide deposits accurately. These deposits frequently cause multiple issues, which often lead to transformer failures. Standard inspections rarely reveal these deposits, as technicians must unwind copper wire and de-oil the paper to see the shiny sulphide deposits clearly. Usually, copper wires display dark or multicolored surfaces, and their discoloration can vary greatly along the entire length of the conductor. Until recently, costly laboratory tests were the only reliable method for detecting corrosive sulfur in transformer oil.
Sulfur exists in transformer oil in different forms and various compounds. Copper sulfides can appear with very diverse characteristics. Because of this, technicians suspect that undetected copper sulfides likely cause numerous malfunctions in transformers and reactors. The portable CS100 Kit offers a rapid, convenient, and affordable testing option.
Common copper corrosion tests refer to established procedures, such as ASTM D1275 Method B and IEC 62535 (the CCD test).
The IEC 62535 procedure, known as the CCD test and formerly named Cigre A2.32.TF01, tests copper conductors by accelerated oxidation at high temperatures. During this process, technicians wrap copper conductors in kraft paper and then perform a visual inspection. This step aims to identify corrosive sulfur compounds, which could contaminate the cellulose insulation with copper sulphide.
The ASTM D1275 Method B also uses accelerated oxidation, but on an electrolytic copper strip at 150°C for 48 hours. Afterward, a visual assessment checks for sulfur compounds that might contaminate copper surfaces. This method provides additional insights, allowing for a more comprehensive understanding of copper contamination risks.
