ABSTRACT:
It has been discovered that the transient voltage which develops on the outer sheath of a coaxial cable under pulse voltage excitation is a result of the inequality between the self inductance of the sheath and the mutual inductance between the sheath and the center conductor. The self inductance of the sheath is always less than the mutual inductance by a small amount because of the finite thickness of the sheath. By manipulating the design of the outer sheath, an equality between the sheath self inductance and the sheath to inner conductor mutual inductance can be achieved which results in a cancellation of the transient voltage on the sheath when the cable is pulsed.
