Essential difference between electrostatic shielding by a conducting shell and magnetostatic shielding is due to. 26125959. 03:48. What is an electrostatic shielding.

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:

Aside from specialized circuit design, shielding is the only method of reducing EMI effects without lowering the performance of complex electronic systems. Shielding can also reduce the rate of circuit path coupling and internal crosstalk within a device by providing an isolated ground reference.

The electrostatic shield is simply a grounded single turn of conductive nonferrous foil placed between coils to divert primary noise to ground.The conductive foil completely enclosing the windings will provide a ground path for primary circuit noise and has the advantage that a very much smaller capacitance exists between primary and secondary c.
