System for Turbine Generator Excitation Winding Shorted Turns Detection KONCAR tg-wfd The TG-WFD system performs analysis of magnetic field in machines air gap. Based on patent-pending solution for differential measurement of magnetic field, system can provide to the user information's on potential shorted turns in real-time. TG-WFD system allows a better asset management and a reliable monitoring of the machine. System Features • On-line analysis • Winding fault detection • Fault location is enabled with key phasor • Data storage • Enables a better asset management • Reduces the potential damage costs TG-WFD system functions • Works with classical fault detection theory and with new patent-pending solution for winding shorted turns fault detection • Long-term data preview for all excitation winding coils • Local and remote data access • Upgradeable system for various monitoring parameters KONCAR Electrical Engineering INSTITUTE
