A protection scheme is proposed for the 3 kV DC railway, in Kwa-Zulu Natal province, a region with high lightning occurrence density. The surge was sought by implementing three metal-oxide arresters and an overhead ground wire. purpose of these determined their location circuit points that are vulnerable to adverse effects: arrester installed protect insulators between lines supporting metallic...

The application of surge-protective devices in lowvoltage systems faces the dilemma of providing effective limiting against surges while not attempting to limit the temporary overvoltages that do occur in a power system The paper illustrates this dilemma with specific scenarios and presents recommendations for reconciling these two conditions through adequate design and more explicit standards.

In his article "Possibilities and Limits of Comparative Literature Today" Darío Villanueva discusses the itinerary of comparative literature and its problematics and queries the discipline's adherence to literary history and its identification with the theory of literature. Villanueva's discussion is with particular reference to Spanish-language works such as by Claudio Guillén's systemic view ...

surge is one of the two destructive factors in compressors. surge is the stream instability phenomenon in compressor that imposes severe damages to the compressors. nowadays, suppressingsurge phenomenon is one of the most important issues in oil and gas industries, especially when flow reduction or gas reflux is considered. according to moore-greitzer compressor model, this paper designs an act...

The connection of diode rectifier (DR)-based wind power plants (WPPs) to existing or planned high-voltage dc (HVdc) interconnectors can lead important savings on cost and system robustness. Since the DR station usually operates in a bipolar configuration, its symmetric monopoles is particularly challenging. However, there are no published detailed studies protection WPPs monopole even interconn...

As far as the design of SPDs is concerned, the need exists for simplifying its circuit structure in fulfilment of the prerequisite condition of protective reliability. The circuit simplification for SPDs is of benefit to lower the cost of manufacture and reduce the size of chassis. Considering that the traditional SPD that has been extensively used on single-phase AC power supply lines requires...

When the mass flow rate through the compressor is reduced at a constant pressure ratio, mass flow rate will drop to an extent that the complete reversal of flow and surge occurs. Recently many research focuses on turbocharger surge, however, there are not enough investigation on the effect of surge on the performance of the turbocharger. The aim of the paper is to investigate the effect of repe...
