Končar Power Trans former s Ltd. A Joint Venture of Siemens Energy and Končar - Smart Digital Assistance

Končar Power Transformers Ltd., A Joint Venture of Siemens Energy and Končar is a Croatian company engaged in the development, design, production, testing, sale, and servicing of power transformers and shunt reactors. They specialize in the production of large power transformers of voltages up to 550 kV and up to 1000 MVA, which are currently exported to more than 90 countries around the world. Transformers are designed to provide maximum grid availability through long lifecycle, maximum efficiency, connectivity, and optimized operation. Each transformer is adjusted to the customer’s needs and on average two products are produced in series. Due to different customer needs, there are no standard parts. To increase sustainability and facilitate the flexibility of production, systems for smart digital assistance, tracking of metal parts and measurements in production have been implemented in production processes. Prior to the implementation of these systems, the necessary digitization and optimization of production processes and infrastructure was carried out. Smart Digital Assistance is a system consisting of a mobile stand and a large touch screen that allows employees easier access to the necessary documents and information in the workplace. The Smart Digital Assistance system currently provides digital information on work orders, technical documentation (drawings, BOMs) and work instructions. New parts of the system are being developed that will enable digital management of checklists, maintenance, and registration of working hours. The Metal Part Tracking system provides current information on the status of deliveries from the supplier and the location of the product in the warehouse. This information is very useful due to the large number of metal parts that make up each product. The system is based on RFID technology, and implemented using fixed antennas, forklifts with RFID and GPS antennas, mobile portals with antennas and handheld readers. Information on the status and location of the product obtained by reading RFID tags is stored directly in the ERP system. The Measurements in production system processes a large amount of data collected from various sensors and thus provides various information from the production process itself such as air quality inside the plant and the condition of machines. Additionally, it enables inspection of input material dimensions and product quality control. In development is the control of dimensions of input materials and semi finished products performed by 3D scanning and automatic comparison with CAD models. Additional sensors are also in development for the product quality control to be performed during the production process using sensors that automatically measure the dimensions of product components. After checking each dimension, the system will automatically enter its status in the checklist.
