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 performance assessment with line arresters [PDF]

Proceedings of 1996 Transmission and Distribution Conference and Exposition, 2002
The paper describes the studies performed by a team of engineers from FURNAS and USP to determine the application conditions, the type and ratings of surge arresters to be installed on a few transmission lines operated by the first-named company in order to improve their performance for lightning strokes.

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.

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.

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.

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.

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.
