most developing countries have achieved productivity growth in economic sectors like agriculture for more than 30 years. universities and governmental research centers have tried to generate knowledge with direct social and economic effects during these decades. so, productivity and production growth can be attributed to technological changes made possible through investment in agricultural res...

An approach for assignment of the optimal location and tap changer adjustment related to flux-lock type superconducting fault current limiters with tap changer (TC-FLSFCL) is used in this paper by debating the reduction of fault current flowing from each device and enhancement of reliability varying with customer type in a distribution network connected with distribution generation (DG). TC-FLS...

In this paper, the impacts of installing superconducting fault current limiter (SFCL)in radial and loop power distribution system are evaluated to improve voltage sag in both cases of with and without distributed generations (DG). Among various SFCLs, the hybrid type with a superconducting element in parallel with a current limiting reactor (CLR) is selected. This is more effective than resisto...

Abstract A miniaturized analog load-checking relay protection test device is developed in this paper, which a high-precision wireless phase volt-ampere configured. This device, characterized by intelligence and ease of operation, realizes the detection transformation ratio, polarity, phase, etc. secondary wiring transformer smart substation merging unit conventional substation. It meets testing...
