Experimental investigation of longitudinal shear transfer in insulated concrete wall panels with notched insulation

Journal of Building Engineering, 2021
Abstract Precast concrete sandwich panels are usually comprised of two concrete layers surrounding rigid insulation. The most commonly used insulation types are extruded (XPS) and expanded (EPS) polystyrene or polyisocyanurate (PIR). Studies have shown that walls with EPS insulation develop higher composite action than walls with XPS insulation ...

High-Frequency Impulse Modeling and Longitudinal Insulation Analysis of Bifilar Superconducting Coil

IEEE Transactions on Applied Superconductivity, 2021
Bifilar coil is one of the most applicable structures used for resistive-type superconducting fault current limiter. However, the turn-to-turn (longitudinal) insulation of the bifilar coil under lightning and switching impulse is rather different from the conventional pancake coil. The longitudinal insulation is characterized as the distributed circuit

A novel diagnosis algorithm of maximum frequency for longitudinal insulation fault of transformer winding

2011 IEEE Power Engineering and Automation Conference, 2011
The transformer, as one of the most important equipment in the transmission and transformation systems, is directly related to the safety operations of the power grid. Because of the longitudinal insulation fault of transformer windings occupied the highest proportion in insulation faults, the research for the longitudinal insulation fault is has ...

Power transformer longitudinal insulation electric field calculation and analysis software

2015 IEEE Magnetics Conference (INTERMAG), 2015
The transformer is one of the most important equipment of the power system, the accident that the lightning impact damages the transformer insulation often happens[1]. The main design method of transformer longitudinal insulation structure design is the wave process calculation which is basis on the transformer electromagnetic optimization design[2] [3]
