8237-1245 Rev. B PROTECH-GII OVERSPEED PROTECTION DEVICE WOODWARD
The ProTech-GII is a configurable Overspeed detection system. Protech-GII is designed to safely shut down steam, gas, and hydro turbines of all sizes upon sensing an Overspeed or over acceleration event. It is available in two dual redundant trip relay outputs using a 2-out-of-3 voted architecture or three independent non-voted trip relay outputs with individual alarm relays, 4–20 mA speed readouts Modbus communications making this Overspeed device easy to integrate into any turbine safety system. This ProTech GII model is a bulkhead mount, high voltage/high voltage, independent relays, voted inputs with math functions protection device for steam turbine protection also.
FEATURES & FUNCTIONALITY OF PROTECH- GII
- Acceleration Detection
- MPU Detection
- MPU Detection
- Sulfur Contamination Resistant
- On-line Repair
The Protech-GII is available in flush-mount models designated to be installed within a standard 24′ cabinet front door. Designed for harsh environments when installed within an enclosure, the device has an ingress protection rating of IP56. Designed for high reliability also.
This fast-acting Overspeed protection device is designed to be applied in conjunction with a turbine control or trip system. Interface with a related control system or plant DCS can be performed via the PROTECH-GII’s redundant hard-wired input and output signals or triple redundant Modbus communication ports to shut down the turbine safely
