Single Line Diagram 275/132kV

Single Line Diagram 33/11kV

Yang sume kt atas nie adalah contoh single line diagram drawing dr 500kV hingga 11kV. SLD nie mewakili sistem kuasa dalam tiga phase(fasa). Sume komponen dlm substation bley diketahui dgn melihat SLD nie termasuk dari primary ke secondary equipment (bdasarkan CT ratio). SLD adalah drawing yg disimplekn. So ia senang difahami.
