Transformer Condition Assessment
We show you what your fleet is made of
Power transformers are critical systems, both in primary substations and in industry. When they fail, they cause great financial damages. To identify units with an increased risk of failure over time, extensive condition assessment is recommended. With the assistance of innovative measuring methods, some of which were also developed in-house, we create a picture of the current condition of your transformer over a short period of time and derive adequate recommendations for action. Thanks to our decades of expertise, you can be confident that you are making the right choice every step of the way.

More Information
Visual inspections are an important part of transformer condition assessment. The visual inspection allows potential problems to be detected early, thereby ensuring reliable service of your equipment over the long term. The visual inspection can be performed immediately without any great effort after service work has been carried out. This eliminates additional service call charges.
Analysis of the transformer oil is a tried-and-tested method for assessing the condition of a transformer. We have a global service network and are happy to take oil samples, which are analyzed in accredited oil labs (worldwide). From these samples, we can derive reliable statements and recommendations for action from the analysis results.
For sampling, we exclusively use our own standardized containers/kits and also provide them to you for your own sampling. On our OILTEST online platform, the results of the analysis are documented extensively, graphically processed and provided to you in our customer portal with many functions.
Surface temperatures can be determined using a thermographic measurement. Thermal radiation, invisible to the human eye, is converted by the thermographic camera into visible thermal images. The measurement process is used to reveal anomalies and damage to your transformer that cannot be determined through other methods. Regular thermographic examination can prevent personal injury and property damage and reduce the failure risk of your system.
Within our test portfolio, we differentiate between routine electrical tests, fault analyses, condition assessments, commissioning and special measurements.
A variety of electrical tests help you get reliable insight on the operating condition of your transformer. For contact problems, partial discharges, mechanical deformations and more, we identify abnormalities with the help of our test portfolio and initiate suitable countermeasures.

TESSA® FLEETSCAN 2D - The digital consulting approach for fleet management of your power transformers
TESSA® FLEETSCAN 2D is a two-dimensional consulting approach for the condition assessment of power transformers. The results of the visual inspection, oil analysis, IR thermography and electrical measurement are taken into consideration to classify the transformer into a 2D matrix. We then create a detailed report with clear recommendations for action to reduce the risk of failure and increase the remaining service life. The budget and resources can thus be allocated in the best way. Learn more about
