Electromagnetic Interference Caused by Parasitic Electric-line Current on a Digital Module in a Closed Cabinet

This paper conducts an electromagnetic analysis of the closed cabinet used for instrumentation and control in nuclear power plants for the case of a parasitic electric-line current that is undesirably generated onto an interior digital module. Based on the Helmholtz equation in conjunction with both...
