Energy transmission is dramatically changing. As grid operators need to manage trends of decentralization and decarbonization, it increases the complexity of their grid networks. These changes are also compounded by increasing challenges, such as aging workforces, environmental, health & safety standards and higher financial profit expectations. The growth of digitalization in other industries has shown its potential in managing similar changes, which inspired Siemens to leverage its state-of-the-art high-voltage products with an innovative digital layer. It was important to deliver a widely applicable solution, which meant easy access, as well as an easily understandable, digital solution conveyed through data analytics tools. The overall goal was to aid pro-active decision-making through this information, without affecting the existing control and protection environment of the grid operator.
A user-friendly experience was paramount to the Sensformer® design; through ease of accessibility, prompt comprehensive breakdowns of a grid asset’s parameters, as well as an operation bearing low additional costs to grid operators. For optimal security, any data transmitted between sensory devices on the transformer and the grid operators would need to be transmitted via a secured IoT device, applying Siemens standards to protect against cyber-attacks and ensure data privacy. And in order to take full advantage of this technology’s potential and to facilitate further innovations, cloud technology and an open eco-system were also necessary for optimizing Sensformer® functionalities.
