Quench energies of potted magnets

The quench energy of potted magnets has been studied for the following two extreme models of the winding: (1) treating it as an anisotropic three-dimensional continuum and (2) ignoring heat conduction in the epoxy and treating it as a one-dimensional continuum. For each model, we have obtained a formula for the point-source quench energy, complete up to a single undetermined constant, by applying a combination of dimensional and group-theoretic arguments to the heat balance equation. The undetermined constant has been estimated by solving the heat balance equation approximately. Correction factors are given for taking into account the source´s being distributed in space and time. The formulas are compared with available experimental data; agreement is fair.
