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 ...

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.

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 ...

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.

Optimization of Surge Arrester's Location
IEEE Transactions on Power Delivery, 2004The lightning surges being considered the most dangerous events in power distribution systems, knowledge of the same allows to obtain a better selection and coordination of protection devices. Moreover, a better knowledge of lightning surges permits to optimize the location of device protection, to reduce the insulation costs of the installations, and ...

2001 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.01CH37194), 2002
The performance of surge arresters during electromagnetic transients on power systems can be simulated with EMTP-type computer programs. This paper discusses the steps to be performed for deriving the parameters needed to represent gapless metal oxide surge arresters in transient simulations.
