TESSA® VACUTAP® Condition Assessment
For maximum availability.
The service life of transformers is steadily getting longer. That is why we help operators make their transformers reliable over the long term. We already have a wide range of asset management solutions, which we continue to develop further. In addition to traditional maintenance and development of solutions for the simple replacement of on-load tap-changers from other manufacturers, we also offer condition assessment of vacuum on-load tap-changers. Even though vacuum on-load tap-changers are maintenance-free up to a high number of tap-change operations, condition assessments can still be useful at certain intervals.
For this condition assessment, we use innovative measurements such as OLTC DGA and a vibro-acoustic measurement (VAM). Our condition assessment can take place both in operation and out of operation.
