This makes a closed conductor shield the inside from outside electric fields. They are useful in protecting sensitive electronic equipment's from stray fields. This effect was first studied by Michael Faraday, and hence closed conductors are often called Faraday cages. Created by Mahesh Shenoy. Questions.

An electrostatic shield, consisting of a single turn of aluminum foil placed between the primary and secondary winding, is used to provide from 30 to 70 dB attenuation of wide band line-to-ground (common mode) noise. Typical uses of shielded isolation transformers include:

The shielding effect can be defined as a reduction in the effective nuclear charge on the electron cloud, due to a difference in the attraction forces on the electrons in the atom. It is a special case of electric-field screening .
