INTERNAL RESONANCE FOR POWER TRANSFORMER INTERACTED WITH CABLE TRANSIENTS

Yanbu Journal of Engineering and Science, 2019
Power transformers may be subjected to switching surges or fault events that may be responsible for internal transformer resonance. This paper deals with two scenarios of cable-transformer resonance.

Overvoltages in MV Industrial Grid under Ground Faults

Energy Engineering and Control Systems, 2019
Medium voltage distribution power grids mostly operate with ungrounded neutral points of transformers. The philosophy of these electrical grids is based on the assumption that they are more reliable than grids with grounded neutral.

Experimental study of a transformer with superconducting elements for fault current limitation and energy redistribution

, 2005
Numerous proposed and developed superconducting fault current limiters and self-limiting transformers limit successfully fault currents but do not provide uninterrupted supplying of consumers. A design investigated in the work combines the functions of a

Overvoltages Transmitted in the Transformer Windings on the Lightning Impulse—An Analytical Method for Determination and Experimental Measurements

Applied Sciences
Overvoltages are brief and significant increases in the voltage level in an electrical system. They can be caused by a variety of factors, but the most common are associated with atmospheric discharges (lightning).
