In this study the effect of core cutting topology in three-phase transformer on its inrush currents is investigated. Two types of similar rating transformers, which have different core cutting topology, were compared experimentally. Transformers are examined by using developed inrush current testing module. Switching firing angle and demagnetization are also considered in the experiment. The inrush...
Rogowski Coil is a current sensor that is often applied to the medium voltage. Rogowski Coil Based PCB Double Helix is a low-power sensor designed to measure the current that can be input into the Gas Insulation Switchgear (GIS). Not only good linearity in the measurement but also wide measurement ranges are needed to measure the disturbances on the power system. Initial signal processing circuit...
This paper presents report on how to implement The Axis Rotation Fast Decoupled Load Flow (ARFDLF) method in the distribution systems. ARFDLF was effective to enhance the convergence of the Fast Decoupled Load Flow (FDLF) method when analyzing a power system with high R/X ratio and it is applied for distribution systems. Distribution systems have some features that challenge the application of FDLF...
