DTH – Distributed Hybrid Transformer technology, awarded the title of Energy Transformation Leader 2026, has reached another important stage of development. The invention developed at Lukasiewicz – Institute of Electrical Engineering has been granted European patent protection. <\/strong><\/p>

Patent No. EP4422010 relates to “A method and system for short-circuit protection of a DVR voltage variation compensator.” Information about the patent was published in European Patent Bulletin 19\/2026.<\/p>

The patented invention is an essential component of DTH technology. It is responsible for the safety of the system’s operation, protecting the compensator from the effects of short-circuits occurring both on the side of the receiver fed from the power grid and in the area of the addition voltage converter. <\/p>

The authors of the invention are Tomasz Sak, Piotr Mazurek, Krzysztof Zymmer and Andrzej Pawlaczyk.<\/p>

The 630 kVA Distribution Hybrid Transformer prototype has been developed for installation in new and upgraded MV\/NV substations. The device is used to stabilize voltage in low-voltage networks and supports applications in modern Smart Grid systems. It enables continuous output voltage regulation within \u00b110% Un, improvement of voltage quality parameters, support for integration of distributed RES sources, and compensation of reactive power and voltage asymmetry within a limited range. <\/p>

The project “Distribution Hybrid Transformer (DTH) as an active component of modern Smart Grid systems” has been funded under Measure 4.1.4 of the Intelligent Development Operational Program.<\/p>

The obtained European patent strengthens the position of \u0141ukasiewicz – Institute of Electrical Engineering as a center developing technologies that meet the real needs of the electric power sector. It is also a confirmation of the implementation potential of the ongoing research and development work and the competence of the teams involved in the development of modern solutions for network infrastructure. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
