Excitation & Governor Systems
For generators and synchronous motors we build static and brushless excitation, digital AVRs and hydro-turbine governors.
SECON-2000
Thyristor static excitation system with digital AVR
A complete excitation system for synchronous generators, with a PLC-based digital controller, thyristor bridge, firing unit, excitation transformer, metering and a touch HMI. It is designed to IEEE 421.1–421.5.
SECON-50 · SECON-30
Excitation for brushless synchronous motors and generators
These low-current systems excite brushless and two-stage synchronous motors and generators. The family also includes excitation control and starters for high-power pumping-station motors.
Generator rotor crowbar protection
A crowbar protects the rotor winding of a synchronous generator from over-voltage and dissipates the energy stored in it. It is usually part of the excitation system, and we design and build each one to order for the generator’s rotor winding.

Digital hydro-turbine governor
The first digital hydro-turbine governor made in Iran, running on a PLC. It controls turbine speed and load, the hydraulic system and servo valves. A plant fitted with it and a Hoorpendar excitation system energized part of the grid in island mode during a black-start test.
