Optimization of Multiple-Layer End-Turn Stress Grading System for High Voltage Turbogenerators

2D spatial optimisation of functionally graded materials used as insulators for field stress control

“…Local field intensification might cause partial discharges or surface discharges, eventually leading to deterioration or failure of the dielectric [2]. Such situations might be avoided through deployment of stress mitigation techniques [3,4]. Several techniques are in vogue, e.g.…”
