Power Factor Corrected rectifiers are a new tendency in development of power supplies. In the last few years, a lot of R&D activities have led to a new category of products for one-phase applications. In this contribution, a new simplified topology is prop ...
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 ...
Voltage sags are one of major concerns in power quality, as they cause serious malfunction of a large number of apparatuses. There are a number of reasons for voltage sags in distribution networks: there is some evidence, however, that in electrical system ...
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 ...
Transient stability investigations consist of studying the rotor oscillations of generators (electro-mechanic oscillations, 0.1-2 Hz) after the occurrence of a fault of large amplitude, e.g. short circuit. The goal is to indicate if the generators are capa ...
The calculation of voltages induced by indirect lightning on multiconductor overhead power lines has been the subject of several studies. The reported conclusions are not always in agreement with each other. In this paper, using a modeling procedure presen ...
The ever-increasing demand for electrical power leads to reinforced power systems. Therefore, the overcurrents resulting from contingencies such as short-circuits are increasingly higher. In order to reduce these overcurrents, a protection system composed ...

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 ...
