Voltage regulation of transformer without load is considered one of responsible and difficult processes of management of working mode of substations. The on-load tap changer (OLTC) supports the main electromechanical loading for this operation. The on-load tap changer is the complex hi-tech electromechanical unit working in conditions: dynamic system with speedwork in a split second, high voltages, high currents and an electric arc, demands precision processing and mating of components, accuracy of the operating mechanism and reliable operation in different climatic zones.
Current state of equipment of production and the applied technologies provides high quality of all manufacturers of OLTC whose production is included into the base list of suppliers of Co. Ltd. “TOGLIATTI TRANSFORMATOR”:
- Co. Ltd. “TOGLIATTI TRANSFORMATOR” (Russia);
- Maschinenfabrik Reinhausen GmbH (Germany);
- Hyndai Elprom Trafo (Korea);
- Shanghai Huaming Power Equipment Co; Ltd (China).
The Quality of design and the main technical characteristics of the same type tap changers are comparable among themselves and ensure reliable operation of the transformer in general.
All tap changers have passed the tests of time in the difficult conditions of the Russian operation and confirm the declared parameters
