Contamination Tests for Lightning Arresters
IEEE Transactions on Power Apparatus and Systems, 1970Contamination 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 ...

The Placement of the Transmission Lightning Arrester (TLA) at 150 kV Network using Fuzzy Logic
International Conferences on Information Technologies and Electrical Engineering, 2018Lightning is one of the main considerations in the causes of the high voltage network’s overhead lines failure. The lightning even also become one of the most dangerous event on the transmission system.

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, 1941Introduction 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, 1907It 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.

Analysis of Surge Arrester Damage Accident on Distribution Line due to Winter Lightning
2019 11th Asia-Pacific International Conference on Lightning (APL), 2019In recent years, surge arrester damage on the distribution line has been drawn attention. The authors analyzed surge arrester damage accidents that actually occurred in the Japanese winter lightning area by simulation and inferred the characteristics of ...
