Finite-Difference Methods for Determining Capacitance Relationships among Arbitrarily Shaped Conductors

Finite-difference approximations are developed for steady state potential problems which contain floating conductors of arbitrary shape. The ability to solve floating conductor field problems underlies the development of two methods for determining the charge- voltage relationship among a set of conductors. A practical example- the modeling of a lightning arrester-is used to illustrate and evaluate these methods.
