1. Modularization of High Voltage Section
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Today, Alstom has several types of High-Voltage sections (HV), which are adapted for every new type of train. Some are very similar in size and components and others are more different. READ MORE

2. The Paradigm Shift for Substations Technology within Wind Power Applications from Onshore to Floating
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Floating wind turbines are attracting more attention as more than three-quarters of the total offshore technical potential is located in deep water, leading to a growing trend in floating wind farm projects. Consequently, it becomes necessary to develop Floating Offshore Substation (FOSS) to step up voltage and efficiently transmit power to the shore with minimal losses. READ MORE

3. Investigation of MIDEL 7131’s Dielectric Breakdown Strength and Thermal Behaviour : Master Thesis, an experimental study using concentric-like electrodes at elevated temperatures to study breakdowns
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Dielectric insulation are constantly exposed to various stresses, while also being expected to last for long periods of time. Naturally, they degrade with use and in demanding operational environments, this degradation phenomena can be accelerated, leading to costly consequences. READ MORE

4. Early Anomaly Detection in Electrical Bushings Manufacturing at Hitachi Energy
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : The manufacturing of electrical bushings for high voltages is complicated and highly demanding technology-wise. This process has more than 10 steps where a single mistake in the chain could cause a complete failure of the final product. A faulty bushing represents high costs to the company both economically and in terms of public image. READ MORE

5. HVDC transformer core resonance calculation
University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikAbstract : Transformers emit a characteristic humming noise due to magnetostriction which is the continuous change in dimensions during magnetization. The noise is amplified if the induced frequencies match the core’s natural frequencies, consequently avoiding geometries that create resonance is critical in order to fulfill customer sound level requirements.
