DETERMINATION OF THE LEVEL OF OVERVOLTAGE IN THE SECONDARY CIRCUITS OF SUBSTATIONS WHEN LIGHTNING IMPULSE VOLTAGE IS DISTRIBUTED IN HIGH-VOLTAGE BUSES

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2017
Lightning voltage impulse due to the waves of storm surge rolling out the high voltage line to a substation causes current to flow in the buses that, due to magnetic effect, induces overvoltage in the secondary circuit.

The loss of an Indigenous‐maintained She‐Oak woodland in southeast Australia

Geographical Research, Volume 64, Issue 3, August 2026.
A 2600‐year multi‐proxy palaeoecological record (pollen, charcoal, and sediment) from Balfour Swamp, east Gippsland, reveals the persistence of an open, grassy She‐Oak woodland maintained by GunaiKurnai. This vegetation community, resilient to climatic variability and fire, was lost following the disruption of Aboriginal land management and replaced by

Leader Propagation Characteristics Under Positive Lightning Impulse Voltages

IEEE Access
Lightning strikes on transmission lines often generate overvoltage, which is the primary reason for insulator string flashover. This overvoltage, with a rapid rise time of just a few microseconds, causes leader propagation characteristics to differ ...
