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 DEVELOPMENT OF APPLICATION TO SOFTWARE ORIGIN PRO FOR INFORMATIONAL ANALYSIS AND FORECAST OF FOREST FIRE DANGER CAUSED BY LIGHTNING ACTIVITY

Міжнародний науково-технічний журнал "Проблеми керування та інформатики"
Forest fires occur for a variety of natural and man-made causes. The main natural cause of forest fires is thunderstorm activity, namely, the impact of cloud-to-ground lightning discharges. It is known that geographic information systems are widely used

Rare Lightning and Convection Characteristics During Two Successive Tornadoes in Southern China

High Voltage, EarlyView.
ABSTRACT Systematic investigations into lightning characteristics of tornado storms in China remain scarce. This study comprehensively analyses rare lightning behaviour and overshooting top characteristics for two successive tornadoes during a long‐lived supercell in southern China on 27 April 2024.

Global distribution of winter lightning: a threat to wind turbines and aircraft

Lightning is one of the major threats to multi-megawatt wind turbines and a concern for modern aircraft due to the use of lightweight composite materials. Both wind turbines and aircraft can initiate lightning, and very favorable conditions for lightning

Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

High Voltage, EarlyView.
ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.

Mechanism of Quasi‐Power‐Frequency Resonant Overvoltage Triggered by Multiple Lightning Strikes in High‐Voltage Alternating Current Systems Equipped With Shunt Reactor

High Voltage, EarlyView.
ABSTRACT This paper investigates the generation mechanism of quasi‐power‐frequency resonant overvoltage triggered by multiple lightning strikes in high‐voltage alternating current (HVAC) systems equipped with shunt reactors. Based on field measurements from a 500 kV AC system, equivalent and simplified circuit models have been established to analyse ...
