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 Currents in Arresters at Stations

Transactions 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 ...

A Proposed Lightning-Arrester Test

Transactions of the American Institute of Electrical Engineers, 1907
It is generally recognized that the worst disturbances to an electrical transmission system from lightning are due to the unbalancing of the circuit-elements after the passage to ground of the initial lightning charge.

The corona as lightning arrester

Journal of the A.I.E.E., 1924
Occasional suggestion has been made in recent years that the properties of the high-voltage corona might be utilized as a protection against lightning and other similar types of disturbance on transmission lines. The idea in these suggestions is that since the ionization attending corona renders the air conductint, the excess voltage following the ...

Lightning Arrester Discharge Currents

Nature, 1948
DURING the last five years an investigation has been made of the discharge currents of a number of 38,000-volt lightning arresters. The transmission system on which these arresters were installed is operated with its neutral point earthed through Peterson coils; the lines are not equipped with overhead ground wires.

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.

Lightning Arrester Spark Gaps-II

Transactions of the American Institute of Electrical Engineers, 1920
This paper describes a new form of high-voltage lightning arrester gap which has been called the ``impulse protective gap'' because of its particular effectiveness in protecting against line disturbances of steep wave front. The paper opens with a brief resume of some of the results of previous investigations of the subject of impulse voltages.

Distribution lightning arrester performance data

Electrical Engineering, 1937
THE intelligent application of lightning arresters requires a knowledge of their performance characteristics under conditions which are likely to be encountered in service. Data have been presented relating to the impulse characteristics of insulation both as used on lines and in transformers.

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 ...

Lightning Current Magnitude Through Distribution Arresters

IEEE Transactions on Power Apparatus and Systems, 1981
The Detroit Edison Company, on behalf of the Electric Power Research Institute (EPRI), undertook a project during 1978-1979 to determine the current magnitude of lightning surges discharged through distribution arresters, and to determine the frequency of these lightning ...
