A modern high voltage laboratory has to be shielded mainly to avoid the electromagnetic disturbances of the partial discharge measurements. The paper describes the practical methods of shielding a high voltage laboratory and introduces a simplified method for shielding calculations which takes into account the effect of the seams, conducting gaskets, short-circuited slots and sound absorbing holes. A numerical example illustrates the results in the case of a large hall. Copyright š 1971 by The Institute of Electrical and Electronics Engineers, Inc.
