- KONCAR - INSTRUMENT TRANSFORMERS Inc. Pref (KONČAR - Mjerni transformatori d.d.) is a Croatia-based electrical equipment manufacturer specializing in the engineering, design, production, and lifecycle servicing of high-voltage and medium-voltage instrument transformers for power transmission and distribution infrastructure. Founded in 1947 and headquartered in Zagreb, Croatia, the company operates as a specialized manufacturing subsidiary of the KONČAR Group (KONČAR - Elektroindustrija d.d.) with its preferred shares publicly listed on the Zagreb Stock Exchange under the ticker symbol KOTR2. The company manufactures and supplies a diverse equipment portfolio that includes high-voltage instrument transformers rated from 72.5 kV to 800 kV, encompassing top-core and inverted current transformers; inductive voltage transformers; capacitive voltage transformers and divider units; combined current and voltage transformers, including the proprietary VAU model line; station service voltage transformers (SSVT) for auxiliary substation power; medium-voltage indoor and outdoor instrument transformers operating from 3.6 kV to 52 kV, insulated with epoxy resin or oil-impregnated paper; and specialized precision equipment, including high-voltage test transformers rated up to 1,200 kV, reference standards, and high-current injection sources. In addition to equipment production, the company provides technical services comprising on-site calibration, insulation diagnostic testing, transformer condition monitoring, commissioning supervision, maintenance, repair, and engineering customization for transmission system operators, power generation utilities, industrial facilities, and engineering, procurement, and construction (EPC) contractors across more than 100 countries globally. In recent developments, the company has expanded its environmental technology offerings through the deployment of its Green Line series, which utilizes biodegradable natural and synthetic ester liquids as insulating media. Operationally, the company secured its largest-ever Austrian supply contract with Austrian Power Grid (APG) to deliver more than 450 high-voltage instrument transformers rated up to 420 kV, alongside securing significant supply contracts across Germany, Lithuania, and the Middle East, resulting in record production utilization and multi-year order book coverage.
