Electrical Measurement for 400kv

2001-3-1substation in Tehran as a 400kv GIS substation in EMTP software. First, very fast transients(VFT) model is used for the GIS substation modeling. Then, voltage signal of different points of GIS substation in presence of PD are measured by use of the PD model in gas insulator and VFT model, until the PD effects on system

The simulation and experimental measurement of electric and magnetic field have been carried out near 20-400kV transmission lines [15].

2020-4-6To meet the requirement, this substation is set up by looping in and looping out (LILO) Bongaigaon-Shilchar 400 kV double circuit line. The 400 kV is then stepped down to 220 kV and it is sent to Agia, Boko and Sarusajai as the outgoing line of the substation. The 132 kV and 33 kV outgoing lines are under
