A method for transformer design with an asymmetric winding configuration to reduce the inrush current with appropriate voltage regulation and short-circuit current is proposed. Differing from the traditional symmetric winding structure in transformer design, this method can provide the high inrush equivalent inductance and suitable leakage inductance ...

OVERVOLTAGE AT THE TRANSFORMER WHEN DISCONNECTING CLOSE ASYMMETRICAL SHORT CIRCUITS
This article examines overvoltages at the inputs of high-voltage (HV) and low-voltage (LV) transformers rated at 110/6 kV and 110/10 kV, focusing on scenarios involving grounded and isolated neutrals during short circuits near the transformers. The study finds that with an isolated neutral, overvoltages resulting from a phase-to-ground short circuit ...Mufidzade, Nahid, Gulgaz Ismayilova

Abstract The fact that a loss of symmetry in the stator currents of a generator produces a second harmonic component in the field circuit is used in the reported work to detect all asymmetrical faults on the stator side, including inter-turn short-circuits.

2019 6th International Conference on Soft Computing & Machine Intelligence (ISCMI), 2019
Asymmetrical three-phase short circuit faults occur more often than symmetrical three-phase short circuits faults. The asymmetrical three-phase short circuit faults can be line-to-line faults, double line-to-earth faults or line-to-earth faults. Symmetric components technique and computer methods like time-domain fault analysis as well as quasi steady ...

2016 Second International Innovative Applications of Computational Intelligence on Power, Energy and Controls with their Impact on Humanity (CIPECH), 2016
Short circuit electromagnetic (EM) forces are considered as important factor and should be taken care of while designing a transformer. The effect of forces is more important in case of large transformers, but the procedure of analysis of forces is same for both power transformers and power distribution transformers.
