The electronic panel can be either standalone or integrated into the automated control system panels of the hydroelectric unit.
The hydromechanical part of the governor can be designed and manufactured for control system working pressures of 2.5 to 15 MPa. Hydromechanical control pillar or separate control unit versions are available. Control pillar versions with electrohydraulic control only and combined versions with electrohydraulic and mechanical control (linkage) are both manufactured. For large Kaplan and Francis turbines, columns and units with main slide valve diameters of 100 and 150 mm, designed for a maximum pressure of 6.3 MPa, are offered. BOSCH-REXROTH hydraulic equipment or equipment designed by Power Machines is used as electrohydraulic converters and slide valves.
Control pillars are installed separately from oil pressure units. Control units are installed on oil pressure unit drain tanks.
Feedback devices are installed directly on servo-motors; precise linear displacement transducers are used. The design does not include any links between moving and fixed components.
The speed signal generator consists of a toothed gear installed on the rotating part of the unit and a number of transducers. The device makes it possible to monitor speed in all operating conditions and to detect dangerously-low speed when the unit is at standstill.
