TL;DR: In this paper, voltage distribution and maximum electric field intensity in power transformer windings, using various electric shields are studied, and the results show that disk-type windings with inter-turn shields have the best voltage distribution under lightning impulse conditions.
Abstract: In this paper, voltage distribution and maximum electric field intensity in power transformer windings, using various electric shields are studied. The study covers disk type and layer type windings. According to the results, disk-type windings with inter-turn shields have the best voltage distribution under lightning impulse conditions.

TL;DR: In this paper, an electrostatic shield is constructed by bending a wire gauze, and composed of an underside section 8A for covering the electrostatic shields disposed onto the underside of a tank, side face sections 8B for covering electromagnetic shields arranged onto the side faces of the tank, and mounting sections 8C for fitting to the tank.
Abstract: PURPOSE:To manufacture an electromagnetic shield easily while relaxing field concentration on the end face of the electromagnetic shield by installing an electrostatic shield covering the electromagnetic shield between an induction apparatus body and the electromagnetic shield. CONSTITUTION:An electrostatic shield 8 is mounted among a winding 4 and electromagnetic shields 5 to a shape that the electromagnetic shields 5 are covered. The electrostatic shield 8 is constituted by bending a wire gauze, and composed of an underside section 8A for covering the electrostatic shields disposed onto the underside of a tank, side face sections 8B for covering the electromagnetic shields arranged onto the side faces of the tank, and mounting sections 8C for fitting to the tank. Accordingly, the wire gauze need not be bent sharply as an edge shape even in a bending section, and the bending section having smooth surfaces can be formed, thus sufficiently reducing an electric field on the electrostatic shield.

TL;DR: In this article, two types of shields, vented cylinder and inverted-U shaped, were constructed from PVC pipe for air temperature data loggers, which were designed to be attached to a swiveling mounting system to avoid damage by animals and eliminate the need for protective exclosure fencing.
