Abstract
Protection of epoxy impregnated magnets requires careful design and analysis of all factors that affect the winding temperature rise before it reaches quench temperature. Among these factors is the AC loss due to current and field change as a result of the current transfer between coils after the protection diodes voltages exceed their critical values. In this paper we look in detail into the effect of all loss components, self-field, hysteresis, and eddy current coupling using the National High Magnetic field Laboratory computer code MAGZIFT.
