Avoid Hazards of the Stator Core Ring Flux Test with ELCID Evolution

IRIS Power Electromagnetic Core Imperfection Detection Test Set - EL CID EvolutionContinuous thermo-mechanical stresses and thermal cycles can have a severe impact on a generators stator core, and over time, this can lead to deficiencies in the core insulation.

With regular checks of the insulation condition it is possible to avoid consequential damage, such as core burning or damage of the bar insulation.

The flux test is used to measure the condition of the stator core insulation and to detect possible local insulation damage. Insulation failure can result in local hot spots between several sheets of the core during magnetization.

The IRIS Power Electromagnetic Core Imperfection Detection Test Set – EL CID Evolution operates at only 4% of normal operating flux, generated by its quickly installed excitation kit.

Any imperfections in the core inter-laminar insulation produce fault currents which are detected by a Chattock coil and analyzed by the ELCID Evolution signal processing unit. Measurement results are digitally stored in the PC for analysis and report generation, and faults can be precisely located in the core. Future results can be compared to past results for trend analysis.

Reduce test outage time and avoid the hazards of the stator core Ring Flux test with the ELCID Evolution.

EL CID Evolution Features:

  • Faster test scanning (up to 120mm/sec @60Hz)
  • Easier excitation calculations
  • Simpler testing with dual Chattocks
