Lightning arrester economics

Electrical Engineering, 1936
Early applications of lightning arresters were hindered not only by high cost, but also by the general lack of knowledge of both the characteristics of lightning and the protective characteristics of the arresters themselves. Present knowledge of these factors, however, achieved as a result of extensive field and laboratory research, has made possible ...

The oxide film lightning arrester

Proceedings of the American Institute of Electrical Engineers, 1918
The oxide film arrester is a new type of lightning arrester made up of a film of insulation in contact with a conducting powder. Upon the application of over-voltage, the insulation will be pierced, but the powder will very rapidly turn into insulation and plug any holes punctured in the original insulation by the over-voltage, thus forming in ...

Lightning arresters for distribution apparatus

Electrical Engineering, 1945
THERE are today two general types of lightning arresters in use for the protection of distribution apparatus. They are the valve type covered by AIEE Standard 28, and the expulsion type, for which AIEE Standards are being formulated. Both have been used widely for many years. Typical specimens are illustrated in Figure 1.
