Generators
The PRANA system analyses the condition of generators functioning in CCPP and steam turbine-based power units, gas piston machines and other power generation sets. The most common types of defect identified by the system:
- rotor and stator winding damage;
- rotor eccentricity, imbalance, misalignment;
- damage to brushes;
- insulation ageing;
- loss or reduction of excitation system efficiency;
- damage to gas turbine startup frequency converter;
- cooling system;
- turbine unit vibration monitoring;
- oil cooling circuits, generator air: efficiency of heat exchangers, seals, leaks.
