Capacitive discharge of metallic structures close to high voltage power lines

A study of capacitive discharge of metallic structures that are close to high voltage power lines has been carried out. An equivalent circuit for modeling the transient capacitive discharge phenomenon is presented and analytical expressions for this transient behavior have been derived. Numerical results have been obtained and compared with published results for initial value of the transient potential and potential peaks after the steady-state conditions have been established. The agreement is excellent. The equivalent circuit model and analytical expressions for the transient behavior of the capacitive discharge process presented in this paper can be easily applied to many practical situations.
