Gas in Oil Analysis | TOGA-100-GC | Dissolved gas analysis (DGA)

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

DGA analysis (Dissolved Gas Analysis) remains a top method for DGA diagnosis in transformers and tap changers. This gas in oil analysis allows early fault detection and plays a key role in DGA condition assessment. As transformers insulating oil and insulation materials age, gases in oils dissolve, especially during thermal or electrical faults. Through oil sample analysis, operators can detect early signs of fault development.

Technicians use DGA dissolved gases as indicators to monitor trends over time. They identify unique gas patterns tied to specific faults. Dissolved Gas in Oil Measurement gives crucial insights into the transformer’s condition. The TOGA 100-GC system supports total gas content measurement for mobile, on-site DGA. It delivers quick, accurate results, identifying gaseous decomposition products linked to fault types. The TOGA 100-GC separates all eleven gas components in a single injection, using the ASTM 3612C standard for dissolved gas analysis with headspace injection.

The M-Labor series gas chromatograph supports analysis of dissolved gases in laboratories with an optional automatic sampler. For field applications, the TOGA 100 Portable enables efficient DGA analysis with a small helium tank, making on-site dissolved gas analysers readily available. Each TOGA 100 GC’s column oven offers high sample throughput, with fast heating and cooling to meet heavy analysis demands.

TOGA GC systems are compact, lightweight, and modular. Their design supports easy upgrades and maintenance. These systems apply the ASTM D3612C method for analysis of dissolved gases. Their accuracy and efficiency in DGA diagnosis make them ideal for transformer health monitoring, setting the standard in oil sample analysis and DGA condition assessment.

Breakdown Analyzer | ÖLPG | Oil Tester

The ÖLPG Oil Tester is a portable “Breakdown Analyzer” designed for on-site oil testing. This device fully automates the breakdown voltage or dielectric strength test for insulating oil, making the process both fast and cost-effective. A critical test for transformer oil quality is the breakdown voltage test: lower resulting voltage indicates lower oil quality. Ultra-light transformer oil testers like the ÖLPG are powerful and ideal for on-site testing, enabling operators to assess insulating oil quality directly, without sending samples to a lab. Immediate action can be taken based on results if necessary.

A quick procedure and shutdown time of less than five µs enable efficient testing. High-contrast display facilitates handling and navigation, while the Breakdown Analyzer also supports non-destructive testing of synthetic, ester, and silicone oils. Breakdown voltage in insulating oils is determined easily by sampling oil directly from the transformer or current transformer, then subjecting it to the fully automated test. Results provide operators with a clear assessment of oil quality, guiding decisions on retention or replacement.

Automatically generated test reports are ready for download as PDFs onto a USB stick. Rapid voltage cut-off ensures safe, non-destructive testing for synthetic, ester, and silicone oils. Pre-defined, fully automated test sequences adhere to current international standards, guaranteeing compliance with legal testing requirements. In conclusion, the ÖLPG Oil Tester represents a significant advancement in oil testing technology. Offering a reliable and efficient solution for operators in need of accurate and timely results.

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

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.
