Transformers with motor-driven tap changers can be controlled with automatic voltage regulators . Actuation of the motor drive leads to a voltage change by one tap. If the difference between actual voltage and set-point exceeds a certain limit, a regulation command (”up”, “down”) is initiated . Beside application of SPRECON-E-C-AVR as a stand-alone device, automatic voltage regulation can be also integrated into a SPRECON-E-C bay computer together with other control functions .
