• ELCID
• fault diagnostics
• interlamination short-circuit
• stator core

Since the interlamination short-circuits in stator cores can cause major damage to electrical machine a great emphasis is placed to detect such faults. ELCID (Electromagnetic Core Imperfection Detector) test is nowadays often used for testing of interlamination insulation in stator cores of large electrical machines. To investigate this relatively young method a laboratory model of stator core was built, which enables measurements and analyses of intentional short-circuits in the core. Interlamination faults were also simulated and analysed using FEM.
