Studies of in-service and laboratory failures of metal-oxide distribution surge arresters [PDF]
, 2003 We describe the findings from tests and inspections of arresters withdrawn from service, the results of laboratory studies with multipulse lightning currents and high temporary over-voltages, and comparisons of in-service and laboratory failure modes. We

High Voltage, Volume 10, Issue 3, Page 673-679, June 2025.Abstract This study focuses on the distribution of high‐resistance media (pores and spinels) within ZnO $\text{ZnO}$ varistors and explores the mechanical and electrical failure mechanisms of varistors under different pulse actions. Micro‐CT technology revealed that the proportion of high‐resistance media in the edge area is much higher than in the ...

High Voltage, Volume 10, Issue 3, Page 546-554, June 2025.Abstract Commutation failure (CF) is an inherent problem faced by line commutated converter high voltage direct current (LCC‐HVDC) technology. To completely solve the problem of CF, we have proposed a novel hybrid commutated converter (HCC) technology based on reverse blocking integrated gate commutated thyristor, which can utilise two methods for ...
