Urządzenia monitorujące stan turbogeneratora
Partial Discharge Testing
Partial discharge monitoring provides information regarding small electrical sparks that occur within insulation due to aging or deterioration. Iris Power solutions allow for planning maintenance requirements before insulation failures or short circuits occur.
Vibration Analysis of Stator Winding End-Windings
Stator Winding Endwinding Vibration caused by winding looseness and thermal cycling can lead to copper conductor cracking within the windings or failures caused by insulation wear. Iris Power solutions provide information regarding the location and severity of endwinding vibration to enable corrective action.
Leakage Test of Stator Wedge
Loose stator wedges can lead to coil vibration and stator insulation erosion. The Iris Power Stator Wedge Tightness Test provides consistent and quantitative means to identify the location and degree of stator wedge looseness, for the purpose of planning re-wedging or other necessary repairs.
Fluctuation of Magnetic Flux Study
Fluctuations in the rotor magnetic flux are a result of the deterioration of the rotor winding insulation, caused by mechanisms such as load changes, thermal aging, and contamination. Iris Power provides solutions for measuring magnetic flux in a generator, in order to plan maintenance requirements.
Core Lamination Integrity Studies
The integrity of the stator core lamination can be degraded by thermal and mechanical stresses. The Iris Power EL CID test detects shorted laminations and is a globally accepted solution for determining maintenance needs.
Voltage Monitoring on the Shaft
Shaft voltage is induced in electric motors and generators due to rotor winding ground faults, surges caused by the rotor excitation system, magnetic generator components, and magnetic fields. Iris Power solutions provide the information needed to plan maintenance ahead of time, helping to avoid damage to generator bearings, shaft journals, couplings, and gears.
