The Smart Device for Voltage Regulation – SDV is an equipment that combines the main functionalities of a voltage regulator relay to the thermal protection and control.
During its operation, the SDV aims to maintain the quality of the voltage in the load, that is, within a certain range of values, programmed by the user. For this, in addition to performing the function of relays 90, the SDV presents a series of applications to meet the most stringent standards in the electrical sector.
In addition, based on the readings of the temperature of the insulating oil and one or more transformer load currents, the SDV performs temperature calculations of one or more windings and acts on the temperature management of the asset (functions 26 and 49).
Finally, Treetech SDV has been specially designed to integrate in a harmonic and complete way with any product that supports the Modbus® (standard), DNP3 and IEC 61850 (optional).
