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 ...

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 ...

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.

The Protection of Solid Insulation by Lightning Arresters

Transactions of the American Institute of Electrical Engineers, 1941
Introduction THE protection of distribution transformers or other apparatus against lightning involves the basic problem of limiting the voltage applied to the insulation to a value adequately below the insulation strength. The effect on insulation of chopped waves and full waves of standard impulse wave shapes such as 1.5×40 microseconds has been ...

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.

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 ...

1922 Developments in autovalve lightning arresters

Journal of the American Institute of Electrical Engineers, 1923
The work done in the past year in developing commercial forms of lightning arresters based on the ``autovalve'' principle is reported. Fundamental data given by Dr. Slepian at the 1922 Midwinter Convention are briefly reviewed. The balance of the paper deals with new material and covers further research, development and test.

New Principles in the Design of Lightning Arresters

Transactions of the American Institute of Electrical Engineers, 1907
The installation of lightning arresters is of the nature of an insurance. A certain percentage of the cost of the apparatus can reasonably be invested as a safeguard in protecting the apparatus. Furthermore, a percentage of the income can also be invested in protective apparatus as an insurance against interruption of service.

The Power Interruption Testing of Lightning Arresters

Transactions of the American Institute of Electrical Engineers, 1951
A special surge circuit has been developed for use in power interruption testing of lightning arresters. This circuit consists of a power source, a surge circuit, and an impulse timing circuit.

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.
