Application
All measurement, control and regulation tasks of tap-changing transformers can be executed using the new REG-DA voltage regulator.
The REG-DA regulator features a world innovation as it is equipped with a high-capacity transformer monitoring function in accordance with CEI IEC 354 (VDE 0536). This function allows the operator to call up information about the hot-spot temperature and the lifetime consumption of the transformer at any time. If required, the regulator can even activate up to six cooling levels. The oil temperature can either be recorded directly (PT 100) or via a mA input.
Apart from its basic function, every REG-DA voltage regulator can be used as a measurement transducer, recorder, statistical unit, paragramer and transformer monitor all at the same time. All important network measurement quantities are displayed in measurement transducer mode. The trends in the voltage that is to be regulated over time and a second, selectable, measurement quantity are shown in recorder mode. The statistical unit for the tap-change position offers a clear presentation of all switching operations of the tap changer. The paragramer provides a complete busbar simulation.
