SpeedSys 200 - Applications

System that are well suited for Wind, Hydro and Steam Turbine Speed Monitoring and Alarming.

FT3000 overspeed protection system replacement

The FT3000 overspeed protection system, formerly supplied by the Jaquet Technology Group (now: TE Connectivity), has been discontinued by the manufacturer. The following is a replacement for the FT3000.

 

Bently Nevada BN3500 with Istec SpeedSys 200 Overspeed Detection System

When an overspeed situation occurs the system should trip the steam turbine to prevent potential damage and dangerous situations. Zero-speed was monitored to prevent the turning gear from starting soon. The turning gear can only be started, when the rotor has come to a complete stop, as this could otherwise damage the turning gear.

One of the relays of a SpeedSys 200 unit was configured to cover zero-speed monitoring, which was a function that was previously covered by the old BN3500 tachometer module.

The BN3500 was replaced with a 2oo3 SpeedSys 200 configuration. The DIN-rail assembly was engineered on-site and consists of the following components:

  • Two 24V power supplies
  • Three GSI 127 galvanic isolators
  • Three SpeedSys 200 modules, hardwired to form a 2oo3 voting structure
