GCM
Generator Condition Monitor
GCM - The most advanced technologies combined in one system
1. Advanced Fault Detection and Diagnostic Technology (MCMSoC)
MCMSoC uses advanced, NASA-developed technology with a self learning capability using the generator itself as a sofisticated sensor. It requires only connection into generators electrical output lines, avoiding the need for specialised sensors. It automaticaly teaches itself about the normal operating environment greatly reducing the specialist skills required of the user.
2. Wireless Rotor Monitor
Using sofisticated micro-radio-transmiter for transmission of measured data makes possible continuos monitoring of vital parameters on the rotor. Thanks to Rotor Air Gap Sensor this is the first method to allow real time measurements of stator geometry under dynamic conditions. Together with rotor temperature sensors fault prevention is now possible and saves cost of major overhauls. (more...)
3. Self-learning Knowledge-based software
Early warnings and simple plain text messages are possible with Self-Learning Knowledge-based Software. In such a way seasonal changes of water or air temperature automaticaly change warning settings allowing early detection of potential problems, long before it reaches maximum limits.
Stator/Bearings Controller
Continuous measurement of Stator and bearings temperature measurement during dynamic conditions allows for early warning and prevention of major faults. Air Gap measurement from the Stator allows accurate monitoring of Rotor geometry and early warnings of impeding failure.
Central Processor Unit
Collects data from all system components and saves to hard disk drive. Makes data available to the Network users for visualisation and postprocessing. Alarm and shut-down function is also available here. Central Processor Unit runs
Real-Time operating System (DOS) making it very reliable and fast.
