This paper adopts the charge simulation method to calculate the level of electrostatic induction in a complete facitities and tight structure of a certain 500 kV ultra-high voltage substation on overall placement.

The relation between work and energy in the electrostatic induction are discussedand the 1/2 - factor in the formula of electrostatic interaction energy when the inductiveinteraction exists are studied.

Using three equivalent principle of spherical live object in its state of electrostatic balance,this paper calculates the electric potential of spherical live object space,with which student get a deeper understanding of the physical potential of electrostatic induction phenomenon.
