  2. 1. Analysis of High-Frequency Electrical Transients in Offshore Wind Parks

    Author : Tarik Abdulahovic; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; very fast transient; surge protection; surge; transient overvoltage; restrikes; prestrikes; breaker; voltage escalation;

    Abstract : In this thesis, a study of high frequency electromagnetic transient phenomena is performed. Models of various components needed for simulations of high frequency transients, such as for transformers, cables and breakers are developed. READ MORE

  4. 2. Characteristic of Surge Transfer Through Transformers : Study of Conventional Distribution Transformer and XLPE Cable Winding Transformer (Dryformer)

    Author : Mighanda Manyahi; Vladmiir Rakov; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Electricity; Esp The Study Of Transients and Discharges; elektricitetslära; ssk studiet av transienter och urladdning;

    Abstract : Wide spread application and dependence on microelectronics based equipment in modern society has necessitated the study of power supply quality problems in low voltage power installations. In spite of improvements in surge protection, sensitive equipment connected to low-voltage side of distribution transformer has continued to fail due to transient voltages that are transferred through distribution transformer from high voltage circuits.
