 | The SDV is a device that combines thermal control and protection with the main functionalities of a voltage regulator relay. Based on readings of the insulating oil temperature and one or more transformer load currents, the SDV performs calculations (thermal image) of the temperature for one or more windings and manages the thermal regulation of the equipment (functions 26 and 49). Additionally, during its operation, the SDV aims to maintain the quality of the load voltage, keeping it within a certain range of values, as programmed by the user. To achieve this, besides performing the role of relay 90, the SDV offers a range of applications to meet the strictest regulations in the electric power sector. Finally, Treetech's SDV was specifically designed for complete and seamless integration with any product that supports Modbus®, DNP3, and IEC 61850 protocols. |
