Multipulse lightning currents and metal-oxide arresters
IEEE Transactions on Power Delivery, 1997Multiple stroke lightning ground flashes can impose surges of exceptional severity on exposed distribution surge arresters. This paper describes a series of tests on metal-oxide (MO) arresters and varistors to study surface flashover mechanisms. The results show that the more likely causes of surface flashover were - plasma generation, manufacturing ...

Lightning Protection of Equipment with Remotely Mounted Lightning Arresters
Transactions of the American Institute of Electrical Engineers. Part III: Power Apparatus and Systems, 19581. 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.

Lightning Arrester Discharge Currents
Nature, 1948DURING 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.

Modern impulse generators for testing lightning arresters
Electrical Engineering, 19421. 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 ...

Pellet type of oxide film lightning arrester
Journal of the American Institute of Electrical Engineers, 1923K. 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.
