Comparison of Dielectric Recovery After Arc Burning in SF6 Gas and Its Potential Alternatives

High Voltage, EarlyView.
ABSTRACT Although sulphur hexafluoride (SF6) exhibits exceptional insulating properties, it is a potent greenhouse gas. Therefore, studying alternatives to SF6 is critical for developing environmentally friendly high‐voltage electrical equipment.

The Impact of Various Contact Structures on the Microscopic Surface Condition of Vacuum Interrupters During Capacitive Switching

High Voltage, EarlyView.
ABSTRACT The double‐break vacuum circuit breakers (VCBs) that utilize series break technology effectively increase the switching capability for capacitive currents, elevate the withstand voltage level, and reduce the likelihood of restrike, all without compromising the breaking capacity for short‐circuit currents.

Study on the Power‐Frequency Arc Extinction Characteristics of Semi‐Closed Short‐Gap Device

High Voltage, EarlyView.
ABSTRACT Multi‐chamber arc‐extinguishing devices have a simple structure and excellent arc‐extinguishing performance; thus, they have attracted considerable attention as lightning protection devices. However, the structural parameters of different models of the aforementioned devices vary, leading to inconsistent protection levels; therefore, the arc ...

THE VIOLENCE OF FULL COST RECOVERY: Financing Water Infrastructure, and the History and Future of Perpetual Crisis in Mombasa

International Journal of Urban and Regional Research, EarlyView.
Abstract Foregrounding the role of finance, this article examines the historical production and future trajectory of the urban water crisis in Mombasa. Drawing on archival research and contemporary fieldwork, it traces how principles of full cost recovery—institutionalized during the colonial period and later reworked through postcolonial ...

ENVIRONMENTAL STATECRAFT AND CHANGING ENVIRONMENTAL POLITICS: Chengdu's Ecological Preservation and Eco‐development

International Journal of Urban and Regional Research, EarlyView.
Abstract This article develops the concept of environmental statecraft to study changing urban environmental politics in China and beyond. Our review of existing conceptions reveals a growing need to account for temporal and geographical complexity. Neoliberal conceptions of eco‐state restructuring are increasingly strained by contemporary geopolitical
