SERVO VOLTAGE STABILIZER (OIL COOLED)

At the core of the Voltage Stabilizer lie the regulator coils. While smaller capacity regulator coils remain uncompensated, their larger counterparts in voltage stabilizers are entirely compensated.
Compensation is a technique employed to limit the inherently high reactance of the long, thin coils used in constructing the 'Reliable' Regulator coil, ensuring it remains at a low value across a range of variations. This limitation of reactance aims to induce a linear variation in the regulator's output voltage throughout its operational range.
Machined onto the faces of the coils are contact pick-up tracks. Depending on the desired output arrangement, these tracks may exist on both sides of the coil or only on one side. Subsequently, the coils find their placement on a core composed of grain-oriented silicon steel laminations. This core, along with the coils, is then integrated into a steel framework, enabling roller contacts to maintain a consistent pressure on the coil faces across the entire operational spectrum.
To achieve the desired variation in output voltage, the roller contacts are shifted along the coil face. These roller contacts are enclosed within retaining assemblies, firmly affixed to a carrier board. The position of the carrier board is upheld by a chain drive system connected to the drive mechanism, which can be either manually or motor-driven.
