Switching of disconnectors (DS) and various faults in Gas Insulated Substation (GIS) causes number of pre-strikes and re-strikes happens. The short duration voltage collapse, traveling surges in busbar causes Very Fast Transient Over voltages (VFTO) and Very fast Transient Currents (VFTC) in the GIS substation. The main challenge is to reduce VFTO and VFTC amplitudes. Several methods have been ...

ABSTRAKTelah dilakukan penelitian untuk menentukan arus listrik dan daya menggunakan pendekatan variasi jumlah resistor sebanyak 100 buah dengan kesamaan nilai resistansi sebesar 10 Ohm yang akan dirangkai seri paralel. Selain itu, diberikan perlakuan variabel tegangan 4 Volt, 8 12 Volt. Pengambilan data penambahan pada setiap rangkaian paralel secara berkala interval kelipatan 5 (lima). Hasil ...

Resistor Network Approaches to the Numerical Solution of Electrical Impedance Tomography with Partial Boundary Measurements

a power divider (pd)/ power combiner (pc) with high quality factor and enhanced output ports isolation using substrate integrated waveguide (siw) technology is proposed. an siw cavity is designed to provide a high quality factor filtering response and an smd resistor is attached between two output ports to realize the high isolation. the value of the applied resistor is calculated by using the ...
