1. Transient Voltage Distribution in Bushing
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : An electrical bushing is one of the most important elements in a power transformer. Steep front surges such as transient impulse voltage from lightning strikes is an inevitable electromagnetic transient mostly happening in power transmission and distribution system. The bushing might lead to be degraded due to such kind of surge. LÄS MER
2. Propagation and mitigation of Very Fast Transient Overvoltage in Gas Insulated Substation
Uppsats för yrkesexamina på avancerad nivå, KTH/Elektroteknisk teori och konstruktionSammanfattning : Very Fast Transients are surge overvoltages created for example when opening or closing a disconnector switch (DS). Because of the very high frequency stress they exert on the equipment and their magnitude (up to 3 pu), they constitute an important issue in the design of ultra-high voltage Gas Insulated Substations.
