High Frequency Model of Power Transformer Bushing for Very Fast Transient Studies
IEEE Access, 2023 Fast and very fast transient overvoltages generally appear during switching operations within electrical substations. The oscillatory nature of such phenomena with frequencies that can reach several tens of megahertz tends to degrade the lifetime of high

Introducing small storage capacity at residential PV installations to prevent overvoltages [PDF]
, 2011 Low voltage distribution feeders are designed for unidirectional energy supply from transformer to consumer. However, the implementation of small-scale PV production units on local utilities may result in bidirectional energy flows.

Effects of cycling on lithium-ion battery hysteresis and overvoltage [PDF]
, 2019 Currently, lithium-ion batteries are widely used as energy storage systems for mobile applications. However, a better understanding of their nature is still required to improve battery management systems (BMS).
