For a large multiterminal HVDC system, it is important for a dc fault on a single branch to not
cause significant disturbance to the operation of the healthy parts of the dc network. Some …

In zinc oxide (ZnO) surge arresters, leakage current usually flows across the arrester under
normal operating condition. Leakage current is one of the factors which contribute towards …

The protection of the wind turbines is one of the significant problems, especially as lightning
strikes the blades. In this paper, the authors bring forward a model in which nine …

Lightning strokes on transmission lines could trigger insulation failure if no protective
measures are taken. Typically, a lightning arrester is used for this purpose. In order to …

The existing models of the Metal-Oxide arresters (MOA) have difficulty covering the behavior
prediction under surges with front time ranging from microseconds to nanoseconds. This …

Resistive leakage current based condition assessment of metal oxide surge arrester (MOSA)
is one of the most extensively employed technique to monitor its degradation. An extraction …

Online condition assessment of surge arresters is necessary for early detection of problems
and subsequent replacement of the device to avoid unplanned downtime and/or damage to …

At present metal oxide arresters find limited applications against very fast transient
overvoltages (VFTOs). To enable these arresters to function effectively against VFTOs, it …

The model of surge arrester, which consists of two nonlinear resistors, connected with each
other via two inductive and a resistive element is studied. To determine the model …

Metal-oxide arresters (MOAs) are used to absorb the electrical energy resulting from
overvoltages in power systems. However, temperature rises caused by the absorbed energy …
