TESSA® FLEETSCAN 2D

The digital consulting approach for fleet management for power transformers

Power transformers are the most expensive and perhaps the most strategic assets in a substation. Accordingly, transformer operators both in the utilities and in industry are drawn to optimize their overall financial performance by maintaining a high reliability and extending lifetime at minimal costs.
With TESSA® FLEETSCAN 2D, you can see the condition of your transformers at a glance and identify critical transformers before problems occur. Asset managers and service managers receive clear, prioritized recommendations for the best possible allocation of budgets and resources.

Two-Dimensional approach

The failure risk index reflects the short-term perspective and addresses service managers and their OPEX budget, while the lifetime consumption index reflects the long-term perspective and addresses asset managers and their CAPEX budget. As a result you can form clusters and derive your maintenance strategy according to the condition of your fleet.
