Cho sơ đồ lưới như hình bên. Biết điện áp định mức của trạm biến áp là 35/10 kV.
Toàn bộ đường dây của mạng dùng loại dây
AC-95 ( r0 = 0,37 Ω/km; x0 = 0,35 Ω/km),
chiều dài cho trên hình vẽ. Đoạn dây 2-4 có
phụ tải phân bố đều với mật độ 600 kW/km,
cosφ=0,8 (tổn thất công suất trên đường dây
và trong máy biết áp cho phép tính gần đúng
với Uđm ở mọi vị trí của lưới).
Yêu cầu xác định chi tiết:
 Tổng tổn thất công suất trên đường dây lưới 10 kV ?.
 Tổng tổn thất điện năng một năm của trạm?

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
