Automatic Voltage Regulator (AVR)



The controllable transformers and reactors with tap changers can be expanded and the most suitable solution is A-eberle REG-D automatic voltage regulators. REG-D automatic voltage regulators have a user-friendly interface with freely configurable and programmable structure.

In addition to voltage regulation, it has six different unique features. With the measurement feature, it constantly compares the limit values ​​with the measured values ​​to send the optimum number of switching commands to the tap changers of the reactors or transformers. The measured values ​​are saved thanks to the recording feature of REG-D automatic voltage regulators and are presented to the system operator as statistical information. Transformers are operated separately or in parallel in electrical networks and industrial enterprises. A-eberle REG-D automatic voltage regulators can control the operation in parallel with the signals received from the switching and protection equipment in order to minimize the circulation currents that will occur during the parallel operation of the transformers. In addition, A-eberle REG-D automatic voltage regulators allow the monitoring of transformer parameters with the help of sensors positioned in transformers thanks to the transformer monitoring module.
