An Approach to Performing Stability Analysis for Power Transformer Differential Protection: A Case Study

open access: yesEnergies, 2022
Differential protection normally detects short circuits and ground faults in the windings of a power transformer and its terminals. Inter-turn faults refer to flashovers among the electrodes that arise only in a similar type of physical winding.

New 5-Phase Concentrated Winding Machine with Bi-Harmonic Rotor for Automotive Application [PDF]

open access: yes, 2014
For a power range from 10 to 30 kW, 5-phase machines are well adapted to low-voltage (48V) supply thanks to their reduced current per phase. For three-phase machines but with higher voltages (>120V), machines with a number of slots per pole and per phase
