Abstract：
 The present invention relates to the research of very fast transient overvoltage for completely enclosed combined electrical appliance. The method is that inside one completely enclosed combined electrical appliance and in one place or several places of conducting pole, through which traveling wave passes, sleeve of magnetic ring(s) is applied to alter and damp the transmission of traveling wave. The magnetic ring is made of ferrite preferably or silicon steel, permalloy, etc. The simple method can reduce the amplitude and gradient of the very fast transient overvoltage.
