RES-2000
Speed Signal Device
Reliable speed and frequency monitoring device for hydro-generator units, supporting automatic operation and protection systems.

Product Overview
The RES-2000 Speed Signal Device is an essential component of single-unit automation for hydro-generator units and plays a key role in automatic operation and protection systems.
Designed specifically for hydropower plants, the device uses an industrial-grade microcontroller as its core control unit. It is a highly reliable intelligent device for measuring and monitoring generator speed and frequency. The frequency measurement signals are taken from the generator terminal voltage transformer and the speed measuring gear disc.
