KONCAR - Model HG-WFD -System for Detection of Excitation Winding Shorted Turns in Hydro Generator
The HG-WFD system performs analysis of magnetic field in machine air gap of turbo generator. Based on patent-pending solution for differential measurement of magnetic field, the system can provide to users information on potential shorted turns in real-time. HG-WFD system allows a better asset management and reliable monitoring of the machine.
