Provides a general-purpose, tall-channel model (GPM-TC), which can be used for the evaluation of wire-wound electrical insulation systems (EIS) where the general-purpose model (GPM) defined in I.S. EN 61857-21 does not offer sufficient space for the electrical insulating materials (EIM) and/or winding wire to be evaluated.
