KONČAR - Instrument Transformers
Eight decades of relentless dedication to innovation and research in instrument transformer manufacturing have earned us an impressive reputation in the industry, both regionally and worldwide.
Success with a global impact
Our instrument transformers operate at power plants across all continents, performing successfully at various altitudes, under different climate and seismic conditions, and even in highly polluted environments.
Every product represents the pinnacle of our distinct expertise and developmental efforts, providing substantial benefits to our customers. We continuously improve the quality and capabilities of our transformer portfolio, evolving with emerging materials and technologies.
HV instrument transformers
HV instrument transformers play a critical role in transmission and distribution networks. They are in insulation of instrument and protective devices from high voltages, as well as to transform measured currents and voltages to a level suitable for instrument and protective devices within a defined accuracy class.
We manufacture them for voltage levels ranging from Um = 72.5 kV to Um = 800 kV, with a transformer life of 50 years.
MV instrument transformers
MV instrument transformers are installed at networks with voltage levels ranging from 3.6 to 52 kV. They are insulated with oil impregnated paper or high-quality epoxy resin, with excellent insulating and mechanical properties, cast under high vacuum.
The range includes four types of devices: epoxy resin current transformers, epoxy resin voltage transformers, oil insulated transformers, and three-phase combined transformers.
Special instrument transformers
We manufacture special transformers for the needs of test stations and laboratories. The design of these devices highlights our expertise and know-how in the field of precision measurement and HV insulation.
Our solution include standard (precision) current and voltage transformers, HV testing transformers, current sources, and HV compensating reactors.
Certificates
We’re accredited according to ISO standards:
Flagship projects
Over the course of March and April 2023, we delivered a total of 186 voltage and combined instruments transformers of 123 kV voltage level for the needs of seven transformer substations operated by
In late 2022, we delivered GREEN LINE transformers to Meralco, the largest private sector energy distribution utility company in the Philippines, with a franchise area accounting for one quarter of
We delivered 72 current and inductive voltage instruments voltage level 420 kV and six current voltage level 123 kV to the Slovenian TSO ELES.
