DC Interference Modeling for Assessing the Impact of Sustained DC Ground Faults of Photovoltaic Systems on Third-Party Infrastructure
Dimitriou, Andreas; Charalambous, Charalambos A. (2019)In grounded photovoltaic (PV) systems, dc leakage to earth is formed by the contribution of the PV modules, inverters, and dc circuitry. Ground faults in such systems occur when there is an unintentional connection between ...

Interpreting Coating Stress Voltages on Underground Gas Pipelines Due To Lightning Strikes on Adjacent Power Lines
Dimitriou, Andreas; Charalambous, Charalambos A. (IEEE, 2018)Lightning flashes on power lines may be the source of electrical and mechanical hazards on metallic pipelines that are buried in the nearby vicinity of these lines. This hazard is usually assessed through the coating stress ...

Wall Fusion of Buried Pipelines Due to Direct Lightning Strikes: Field, Laboratory, and Simulation Investigation of the Damaging Mechanism
Charalambous, Charalambos A.; Dimitriou, Andreas; Kioupis, Nikolaos; Manolis, Theagenis; Kokkinos, Nicholaos D. (2020)Wall fusion of buried pipelines can occur if the driving voltage and available current is sufficiently high. For example, it can occur from direct lightning strikes to earth, close to the pipelines' routing. However, not ...
