Lightning Currents in Arresters at Stations [PDF]

open access: possibleTransactions of the American Institute of Electrical Engineers, 1940
A large number of people in several organizations have contributed to make an investigation of this type possible and to correlate the data in suitable form for presentation. The authors wish to express their appreciation to the Ohio Power Company, the Appalachian Electric Power Company, the Atlantic City Electric Company, and the Indiana and Michigan ...

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 ...

New lightning arrester standard

Electrical Engineering, 1950
FOR THE PAST several years there have been three separate AIEE Standards bearing on the lightning Protective devices field: Report on Proposed Standard for Protector Tubes, AIEE 24, July 1940; American Standards for Lightning Arresters for A-C Power Circuits, AIEE 28, May 1944; and Proposed Standard for Expulsion Type Distribution Lightning Arresters ...

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.

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 ...

The international standardization of Lightning Arresters

Electrical Engineering, 1959
It can be concluded that the IEC Recommendation and the ASA Standard for valve-type lightning arresters contain essentially the same provisions. The IEC Recommendation, however, specifies maximum arrester protective levels and differs in other minor respects from the ASA Standard.

Contamination Tests for Lightning Arresters

IEEE Transactions on Power Apparatus and Systems, 1970
Contamination deposits on arrester housings when wetted can cause external flashovers and, by disturbing the voltage distribution on the internal gaps, can lower the power frequency sparkover of the arresters. It has been found that the conditions that produce the lowest external flashover often do not cause the greatest reduction in sparkover ...
