WOODWARD 8237-1369 ProTech-GII Overspeed Protection Device

The Woodward 8237-1369 is a ProTech-GII overspeed protection device designed for steam, gas, and hydro turbines of all sizes. It plays a critical role in ensuring the safety and reliability of turbine operation.

Function:

• Overspeed Detection: Continuously monitors the turbine speed and triggers a safe shutdown if the speed exceeds a predetermined limit. This helps prevent catastrophic failures caused by excessive rotation speeds.
  
• Configurable Trip Settings: Allows setting specific overspeed thresholds and response times to suit the characteristics of different turbines.

Specifications:

• Power Input: High voltage (HV) and low voltage (LV) power supply options for flexibility in various electrical configurations.
  
• Output: Dual redundant trip relays with a 2-out-of-3 voting architecture for enhanced reliability. This means that at least two out of the three relays need to trip to initiate a shutdown, reducing the risk of spurious trips.
  
• Alternatively, some models might offer three independent non-voted trip relays with individual alarm relays for more granular control.
  Speed Readouts: Provides a 4-20 mA signal proportional to the measured speed for monitoring purposes. This signal can be integrated into control systems for visualization and data logging.
  
• Communication Protocol: Supports Modbus communication protocol, allowing for integration with supervisory control and data acquisition (SCADA) systems for remote monitoring and control.

Features:

• High Accuracy: Designed for accurate speed measurement to ensure reliable overspeed detection.
  
• Conformal Coating: The use of a conformal coating material makes the device resistant to sulfur contamination, hydrogen sulfide (H2S), and sulfur dioxide (SO2) gases, which are commonly present in power plant environments. This coating protects the internal electronics from corrosion and ensures reliable operation.
  
• Triple Modular Design: Utilizes a modular design with A, B, and C modules. This enables replacement of individual modules while the device is powered on, minimizing downtime for maintenance.
  
• Panel Mount Design: Intended for mounting on a panel within the control room or switchgear for easy access and visibility.

Applications:

Power Generation Plants: The Woodward 8237-1369 is a vital safety component in power generation plants using steam, gas, or hydro turbines. It ensures the safe and reliable operation of these turbines by preventing overspeed events that could lead to equipment damage or personnel injury.
