Voltage Regulation The a-eberle product range incorporates: voltage regulation on transformers with tap-changer, regulation of Petersen coil (choke coil), ground fault tracing in medium and high voltage system and calibration and simulation of multiple-wire systems.
A-Eberle have entrusted Protection and Monitoring Systems to market, deliver and service their products within Australia.
The voltage regulator works autonomously. The set point and actual value, the regulative deviation as well as the tap-change position are shown on the display (LCD). Moreover the net quantity values, the temporal course of the net voltage, either continuously or after an event or the number and the kind of switching operations made can also be displayed.
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 on 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.
State of the art Interface Power Quality type PQI-D for Medium and High voltage networks is the pivotal component of the systems to measure, monitor, control and record network electrical parameters and quantities. PQI- D can be used as Power- Quality- Interface compliant to DIN EN 50160. It can also be used to measure all electrical parameters in the AC electrical networks.

Power transformers are key components for electrical supply systems. The breakdown of a transformer not only brings a lot of economical disadvantages for the energy supplier, but can also result in extreme losses for the consumer. For this reason, close monitoring of the transformer is recommended as well as a recording of its "temperature curve" (thermal image) to gain information on the current load and the remaining lifetime
