Surge Arrester Protection and Very Fast Surges
IEEE Power Engineering Review, 1983The results of this paper suggest that surge arrester protection may not be adequate for very fast rates of rise of lightning currents even considering insulation strength greater than chopped-wave. Additionally, it is shown that prediction of the magnitude and front time of the peak overvoltage is a complex function of lead length, arrester model ...

Evaluation of Surge Degradation of Metal Oxide Surge Arrester
IEEE Transactions on Power Apparatus and Systems, 1982The surge degradation of zinc oxide elements under a constant ac stress is investigated experimentally. The results are summed up in a set of formulae and figures from which the degradation of any given condition can be evaluated. The increase ratio of leakage current from the initial value is successfully sed as the indicator of degradation of ...

Device for diagnostic monitoring of surge arresters [PDF]
Russian Electrical Engineering, 2008 Basic reasons for the failure of nonlinear surge arresters are considered; most widely spread methods and devices for diagnostic monitoring of nonlinear surge arresters in the course of their operation are analyzed, and a new monitoring device registering discharge current pulses caused by lightning and switching voltage surges is proposed.

IEEE Transactions on Electrical Insulation, 1986
The MOSA (Metal Oxide Surge Arrestor) comprising ZnO non-linear elements has been taking the place of the conventional gapped arresters on a world-wide scale. The ZnO non-linear element was developed in Japan and the application for the surge arrester was also established in Japan for the first time.

IET Generation, Transmission & Distribution, 2020
This study introduces an arrangement of surge arrester, Rogowski coil, and triac to attain service continuity of distribution networks. This new arrangement is proposed to limit the arrester failure due to lightning flashes striking distribution feeders.

Performance Analysis of HVDC Lines Using Surge Arrester
2020 International Conference on Emerging Frontiers in Electrical and Electronic Technologies (ICEFEET), 2020The paper shows a comparative harmonic analysis with surge arrester as well as without surge arrester at the inverter side for LCC (Line Commutated Converter) based HVDC system. Harmonic analysis has been done based on both conditions i.e.

Pollution Performance Of Metal Oxide Surge arresters [PDF]
TENCON '91. Region 10 International Conference on EC3-Energy, Computer, Communication and Control Systems, 2005 A metal oxide surge arrester (MOSA) under the effect of conductive pollutants presents two problems namely the insulation performance of the porcelain housing which is more or less similar to insulators working under polluteted condition. Modelling of this type of problem has drawn considerable attention of the researchers and resultq have been ...

Development Of A Non-Fragmenting Distribution Surge Arrester
IEEE Transactions on Power Apparatus and Systems, 1984Failure of a distribution surge arrester can result in fracturing of the porcelain housing. Although the probability of an arrester failure is extremely low, the cumulative number of failures could be substantial because of the large number of arresters installed.
