Steam Turbine Controls
The majority of overspeed events occur while testing unreliable mechanical overspeed mechanisms. EthosEnergy decreases risk to personnel and the plant with its mechanical and electrical expertise to design, manufacture, and install electronic overspeed systems.
EthosEnergy has multiple OEM turbine experience in designing new speed sensing brackets and sensors. Over years of operation and upgrades, customers have added electronic thrust monitoring, eccentricity, or keyphasors on the turbine shaft. These repeatable designs are customized for each unit to incorporate these additions.
Industry standards API 612 and API 670 are closely followed, including two-out-of-three electronic overspeed switches, independent sensors from the governor, and redundant trip solenoids.
