PD and Condition Monitoring

PD and Condition Monitoring

Kingsly is in partnership with IRIS Power-Canada for their range of product and services in India. Products such as Partial Discharge (PD) Monitoring and other condition monitoring systems use highl evolved automatic interpretation and analysis software, allowing incipient faults to be detected and major shutdowns prevented. Thereby effectively increasing the relaibility and life of the system.

Condition Based Monitoring - Partial Discharge

Insulation failure is one of the principal causes of forced outages for generators, motors, switchgear and dry type transformers which result in considerable damage and lost revenues. Partial discharges (PD) are small electrical current sparks that occur in the high voltage electrical insulation in stator windings whenever there are small air gaps or voids in or on the surface of the insulation. As a stator winding deteriorates from coil winding vibration in the slot, operation at high temperatures, or contamination, the partial discharge activity increases. Thus partial discharge monitoring can be used to detect the primary causes of stator winding failure and generally give two or more years of warning of a machine failure.

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.

Condition Based Monitoring - Mechanical Vibration

Online monitoring of shaft and bearing vibration in hydraulic turbines and generators can help identify various undesirable conditions including unbalance, misalignment, looseness, bearing wear, rubbing, hydraulic problems, electrical problems, resonance, and eccentricity of rotating parts .

The Veski CoDiS (Computerized Diagnostic System) makes it possible to monitor the status dynamically during machine operation. Machine condition issues resulting in vibration can be identified and corrective action taken well before failure. The platform can be expanded to include rotor magnetic flux as well as air gap for a more comprehensive monitoring system of the geometry and dynamic properties of hydro generators.
