Dear Readers,

Transformation is one of the notions that permeates the core of our industry. Although energy transformation made possible the transmission of electric energy from the place of production to remote places of consumption, thus enabling the development of the society to reach the stage we are at today, impacting and improving the life of billions of people worldwide, it was only when it acquired the prefix digital that the concept of transformation got wider popularity.

However, digital transformation has different implications from energy transformation, and today, this concept forms an essential part of all significant business analyses and strategies. One of the definitions of digital transformation is that it is a profound business and organizational transformation whose aim is to fully leverage the opportunities of a mix of digital technologies in a strategic and prioritized way, with present and future shifts in mind.

Industry 4.0 is one example of the digital transformation of manufacturing, whose impact can also be witnessed in our field. Examples of Industry 4.0-related products, which to a certain extent enable digital transformation in our field, are machines used in transformer manufacturing process, such as winding machines, core cutting and stacking machines, test systems, etc. These products can communicate and share data with other machines, processes and systems for monitoring, control and analytics.
