Cable termination - QuickField simulation example
Electric field strength distribution in a cable termination, identifying the highly stressed regions of the cable insulation and termination geometry., and special measures should be taken to limit the field strength and assure safe and reliable operation. Two conductor high voltage cable terminations may be simulated with QuickField using 3D Extrusion approach.
