Abstract

Applicable to devices for surge protection against indirect and direct effects of lightning or other transient overvoltages. These devices are called surge protective devices (SPDs) and are designed to be connected to 50Hz a.c. power circuits, and equipment rated up to 1000V r.m.s. Performance characteristics, safety requirements, standard methods for testing and ratings are established. These devices contain at least one nonlinear component and are intended to limit surge voltages and divert surge currents.
