Abstract

The response of an overhead wire illuminated by a simulated nuclear electromagnetic pulse (NEMP) was experimentally investigated. The wire is 70 m long, 7 mm in diameter, and situated 5 m above the ground. It is located 20 m away from a hybrid-type EMP simulator. The simulator is a resistively loaded elliptical loop structure with its pulse generator located 20 m above the ground. The overhead wire is terminated with various combinations of short circuit, open circuit, and characteristic impedance at the two ends, and the current response is measured at one end and in the middle. The measured responses are compared with calculated values from available analytical models
