In this paper, we investigate the effect of periodically-grounded shielding wires and surge arresters on the attenuation of lightning-induced voltages. We discuss the adequacy of the commonly made simplification of assuming the shielding wire at ground pot ...
This paper presents experimental results obtained at the International Center for Lightning Research and Testing (ICLRT) at Camp Blanding, Florida during the smnmers of 2002 and 2003. Currents induced by triggered and natural lightning events were measured ...
The appraisal of the response of distribution networks to the excitation of lightning electro magnetic pulse (LEMP) requires the availability of accurate models of LEMP-illuminated lines. These models should be able to take into account the presence of shi ...
We present in this paper experimental results obtained at the International Center for Lightning Research and Testing (ICLRT), Camp Blanding, Florida, where currents induced by triggered and natural lightning events were measured at one end of a shielded b ...
Due to the turning on or off operation of the circuit breakers and the disconnected switches, a strong electromagnetic interference in gas-insulated substations (GIS) is commonly generated. The transient wave process with a very wide frequency range can ge ...
Three subsize NbTi cable-in-conduit conductors have been tested in SULTAN test facility. The conductors are identical in the cable layout but they are different in transverse resistance: either SnAg strand coating without wraps, or Ni strand coating withou ...
While most of the emphasis has been focused on the radiated threat represented by intentional electromagnetic interference, it is clear that the threat from conducted disturbances should not be neglected. Conducted threats include those that are produced b ...
Due to the opening or closing operation of circuit breakers and disconnected switches in gas-insulated substations (GIS), a very strong transient wave process can be generated along the three-phase transmission system and transient electromagnetic field ca ...
Besides the option of HTS cables as retrofit elements in densely populated areas, the technically most attractive aspect of HTS is the possibility of high power transmission at reduced voltage. In this paper we concentrate on this second aspect. High power ...
Lightning-induced voltages in power and communication systems are nowadays one of the main causes of power quality and electromagnetic compatibility. In recent years, due to the increasing demand by customers for good quality in the power supply along with ...
