P100C-SX AVR for brushless excitation & static excitation
P100C-SX
We offer state-of-the-art digital P100C-SX Automatic Voltage Regulators (AVR). The solutions developed and implemented by Institute of Power Engineering, Gdańsk ensure full hardware redundancy both at the level of the voltage regulator controller.
These systems can be used for Brushless Excitation or Static excitation system.
The AVR can be applied to new and retrofit applications on gas, steam, and hydro turbine driven generators of any type.
We as excitation system manufacturer commited to provide best solution to end user.
