Structural Features and Working Principle
5.1
This series of voltage regulators consists of a column regulator, a compensating transformer and a controller or a
control circuit, which constitute a closed-loop control system. It is an electrical device that can stabilize the output voltage
through automatic regulation.
5.2
The voltage regulator has a mains function and a voltage regulation function. For details on functions, please refer to
7.4 Commissioning.
5.3
For the working principle diagram of the voltage regulator, please refer to Appendix 1 Electrical Schematic Diagram
10~14.
