Contributions of single-phase rooftop PVs on short circuits faults in residential feeders [PDF]
2014 Australasian Universities Power Engineering Conference (AUPEC), 2014 Sensitivity analysis results are presented to investigate the presence of single-phase rooftop Photovoltaic Cells (PV) in low voltage residential feeders, during short circuits in the overhead lines. The PV rating and location in the feeder and the fault location are considered as the variables of the sensitivity analysis.

Simulation and Analysis of Internal Short Circuit Fault, Electromagnetic Forces and Thermal Analysis of Single Phase Transformer [PDF]
, 2022 Transformer is an essential part of power system which is a vital link between generating station and the utilities. The failure of the transformer results into huge loss of revenue. If the cause of the failure is detected at early stage then the transformer can be saved from complete outage which also increases the reliability of the supply.
