PARTIAL DISCHARGE MONITORING
Partial discharge monitoring can be performed as an off-line quality control test during machine outages or more commonly through online monitoring during normal operating conditions. Iris power provides the partial discharge sensors (epoxy mica capacitor or stator slot coupler), monitoring instrument and diagnostic software to monitor partial discharges and understand the true condition of the insulation.
MECHANICAL VIBRATION MONITORING
Online monitoring of shaft and bearing vibration to identify various failure mechanisms including unbalance, misalignment, looseness, bearing wear, rubbing, hydraulic problems, electrical problems, resonance, and eccentricity of rotating parts prior to failure.
ENDWINDING VIBRATION MONITORING
Stator endwinding vibration monitoring provides advanced warning on potential failures caused by increased vibration with the loosening of insulating blocking and bracing material that shrinks with aging.
ROTOR FLUX MONITORING (SYNCHRONOUS MACHINES)
Rotor magnetic flux variations are the result of the degradation of the rotor winding insulation by mechanisms like load cycling, thermal aging and contamination. Iris Power provides solutions for measuring the magnetic flux in the generator in order to plan maintenance requirements.
AIR GAP MONITORING
Monitoring the air gap between rotor and stator winding of Hydro Generators can help identify many geometric problems including misalignment, magnetic unbalance, rotor shorted turns, loose pole and stator movement that would otherwise lead to damage from magnetically induced heating or rotor-to-stator rub.
OFFLINE TESTING
Offline testing solutions to determine the condition of stator windings, stator core and rotor in generators and motors
SHAFT VOLTAGE AND CURRENT MONITORING
Shaft monitoring to indicate the presence of high levels of voltage or current on the motor or generator shaft in order to detect poor grounding shaft performance prior to bearing failures.
ROTOR FLUX MONITORING TURBINE GENERATORS
Online monitoring of shaft and bearing vibration to identify various failure mechanisms including unbalance, misalignment, looseness, bearing wear, rubbing, hydraulic problems, electrical problems, resonance, and eccentricity of rotating parts prior to failure.
