Dear Readers,

You are holding in front of you our Special Edition on Substations. This topic is the result of our readers’ choice and I think this is a good opportunity for all of us dealing with specific products, to look at the big picture and the conditions in which these products are made – substations.

This issue confirmed once again that digitalization is the dominant trend which enables new opportunities and imposes new challenges for power products. The first conclusion would be that monitoring as we know it, will slowly cease to satisfy practical needs. Power products must be, starting for their design, increasingly able to communicate with other devices and systems in the power gird which comprise the Internet of Things (IoT). The great number of such devices in the network generates big amounts of data and that data needs to be transferred, processed, and stored safely. Cybersecurity comes out of the security standpoint, and, operationally, Big Data arises. The interview with Goran Leci dwells more on the topic of cybersecurity of the critical infrastructure.
