The surface charge accumulation is very likely to trigger the surface flashover, which limits
the large-scale application of DC GIL/GIS. This article comprehensively reviews the effect of …

This article investigates the partial discharge (PD) behavior of protrusion defects in real-size
high-voltage direct current gas insulated switchgear (HVDC GIS) for SF6 and SF6 alternative …

Understanding a partial discharge mechanism at direct current (DC) is an actual research
topic that requires both modeling, simulations and measurements. This paper describes an …

Undetected partial discharges (PDs) are a safety critical issue in high voltage (HV) gas-
insulated systems (GIS). While the diagnosis of PDs under AC voltage is well-established …

The behaviour of partial discharge as consequences of an alternating current (AC) is
already well defined. AC partial discharges have completely different behaviour …

With the growth of the world's population and faster-developing industries, larger amounts of
electric energy are needed [1–6]. To reduce Joule losses at longer distances, voltages …

Undetected partial discharges (PDs) are a safety critical issue in high voltage (HV) gas
insulated systems (GIS). While the diagnosis of PDs under AC voltage is well-established …

Gas insulated transmission lines (GILs) are used in electrical systems mainly for power
transmission and High Voltage substation interconnection. In this paper, we focus on the …

Due to the rapid development of DC power transmission technology, HVDC gas insulated
transmission lines (GIL) and gas insulated switchgear (GIS) are considered as potential …

This study investigates the effect of long-term corona discharge on the physical and
chemical characteristics of protrusion defects in high-voltage alternating current for C 4 F 7 N …
