The SEWs are structures that protrude from the stator and they are not mechanically supported. Hence, they become susceptible to bending stresses and vibration; they flop like wings of a bird. The SEW vibration is the main actor that leads a turbine generator to eventual breakdown.
By adopting TG-Guard as your Condition Monitoring (CM) tool, the user is able to monitor the negative effect trend of the 2xLF from the SEW locations. As modern generators become larger such as supercritical generators, the force of SEW vibration is also larger and more destructive. The TG-Guard also monitors temperature at one location to warn of overheating conditions.
Key Features:
• Wideband sensor working from 20 Hz to 500 Hz.
• Easy and rapid installation (one day for the 16 channel sensors).
• 5 years warranty;5 years of software support and upgrades.
• Immune to EMI and high voltages.
• Fiber Optic making the VibroFibre spouses Telcordia standard.
• Adapted to hostile environment such as extreme temperatures, pressure, high voltage and corrosive environment.
• Signal Conditioner possesses an analog electrical output for direct measurement.
• A SCADA device can be linked to the signal conditioner as it also outputs RS-485 Modbus signal.
• An User Interface is provided for both on-line evaluation (TG EYE) and off-line trending (TG SAFE).
• The TG Guard system can be extended to other types of assets and conditions.
