Description
8237-1600 WOODWARD Overspeed detection system
Technical Requirements:
Measurement of acceleration
ProTech-GII can also be configured to protect turbines from high acceleration events. The derivative of the velocity signal is used to detect turbine acceleration and issue the relevant trip command.
Main machine detection
The speed sensor inputs in each module use special MPU open circuit detection circuits to verify that the MPU is properly connected prior to turbine operation, and special speed loss detection logic to verify MPU function during turbine operation.
Automatic overspeed test program
Optionally, ProTech-GII can be configured to perform routine overdrive tests on each module and then record and report the results. Through this test routine, each module completes its test sequence using an internal frequency generator to simulate overdrive conditions.
Resistance to sulfur pollution
ProTech-GII uses a special conformal coating material that demonstrates excellent long-term protection against H2S and SO2 gases in the international standard IEC 721-3-3 1994 – Environmental Grade 3C2.
