Metal Oxide Conductors for Protecting Power Utility Networks from Excessive Voltage.

In recent years metal oxide conductors have proven their value in networks of power utilities. These conductors are typified by a low protection level, above all in the area of excessive impulse voltages, and by their high energy capacity. With the aid of a digital computer programme the authors simulate two examples from the field of atmospheric excess voltage and impulse excess voltage under consideration of metal oxide conductors. With the voltage progressions so determined, they evaluate the stresses on the components.
