Description:

Voltage can build up across the oil film of bearings until a discharge occurs. Repeated discharge and arcing can cause a pitted and roughened bearing surface that will eventually fail through accelerated mechanical wear. The VTUR / TTUR can continuously monitor the shaft-to- ground voltage and current, and alarm at excessive levels. Test circuits are provided to check the alarm functions and the continuity of wiring to the brush assembly that is mounted between the turbine and the generator.

The existence of flame either can be calculated from turbine parameters that are already being monitored or from a direct interface to Reuter Stokes or Honeywell-type flame detectors. These detectors monitor the flame in the combustion chamber by detecting UV radiation emitted by the flame. The Reuter Stokes detectors produce a 4-20ma input. For Honeywell flame scanners, the Mark VI supplies the 335Vdc excitation and the VTUR / TRPG monitors the pulses of current being generated. This determines if carbon buildup or other contaminates on the scanner window are causing reduced light detection.

The VGEN card serves a dual role as an interface for 3 phase PTs and 1 phase CTs as well as a specialized control for Power-Load Unbalance and Early-Valve Actuation on large reheat steam turbines. The I/O interface is split between the TGEN Termination Board for the PT and CT inputs and the TRLY Termination Board for relay outputs to the fast acting solenoids. 4- 20ma inputs are also provided on the TGEN for monitoring pressure transducers. If an EX2000 Generator Excitation System is controlling the generator, then 3 phase PT and CT data is communicated to the Mark VI on the network rather than using the VGEN card.

The IS215VCMIH1B module excels in controlling voltage signals, allowing for precise regulation of voltage levels. It provides accurate control over voltage outputs, enabling seamless integration with equipment and systems that require voltage control for optimal performance.

The module supports a wide input and output voltage range, accommodating different voltage levels required by various equipment and systems. It can handle a range of voltage inputs and provide regulated voltage outputs, ensuring compatibility and flexibility in diverse industrial environments.

The module incorporates advanced fault detection and protection features. It continuously monitors voltage signals and output states, detecting abnormalities or fault conditions. It can trigger appropriate protective actions, such as alarm activation or equipment shutdown, to prevent further damage and ensure operational safety.
