Cross Sensor Platform for Transformer Monitoring Applications

The current developments in the energy system especially the increased integration of renewable and the introduction of dynamic loads lead to a decoupling of consumption and production and constitute a challenge for traditional grid operation. Digitalization is one of the major tools for grid operators to tackle these challenges, as it allows them to implement flexible and advanced operation and planning strategies, which reduce costs while increasing service security. In the context of operation, transformers represent one of the most important assets in the transmission grid. Their optimal utilization is of utmost importance to ensure its operation for dependable feed-in. The article presents a mobile sensor platform with corresponding back-end solution for developing a novel minimal invasive transformer monitoring approach, designed to complement existing strategies to enable continuous monitoring applications.
