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.

Long-duration surge testing of lightning arresters

Electrical Engineering, 1951
A METHOD OF long-duration surge-withstand design testing of station-type lightning arresters is proposed for consideration by the industry. The test method involves successive applications of a surge having an essentially constant magnitude and a duration measured in thousands of microseconds.

Pellet type of oxide film lightning arrester

Journal of the American Institute of Electrical Engineers, 1923
K. B. McEachron: The pellet arrester represents an extension of the oxide film principle in an ingenious manner. The problem of making, commercially, small pellets of lead peroxide, and coating them with litharge has been solved in a satisfactory manner.

Modern impulse generators for testing lightning arresters

Electrical Engineering, 1942
1. Thorough testing of lightning arresters requires a wide variety of impulse-current waves. 2. The strictly mathematical calculation of circuit constants to produce such waves is limited to the few cases where the circuit resistance is constant. 3. Valve-type lightning arresters have a resistance that is intentionally a function of voltage or current ...

Lightning Protection of Equipment with Remotely Mounted Lightning Arresters

Transactions of the American Institute of Electrical Engineers. Part III: Power Apparatus and Systems, 1958
1. The curves apply to any type of modern lightning arrester. Only the sparkover voltage has to be known; this should be obtained from the manufacturer. 2. When the arrester is between the equipment and the surge, the maximum voltage at the equipment approaches 200% of the arrester sparkover voltage.
