SPD 40KA isixhobo sokukhusela isibambisi sombane

SPD 40KA umbane wokubamba isibambi sombane isixhobo sokukhusela umfanekiso obonakalayo

SPD 40KA isixhobo sokukhusela isibambisi sombane

Inkcazelo emfutshane:

Uluhlu olufanelekileyo

I-TU2 SPD iqheleke ngokunxuseneyo idityaniswe kwisekethe yangaphambili yesixhobo sesekethe esifunekayo, ngokusondeleyo kangangoko kunokwenzeka kwitheminali yesekethe esezantsi. I-SPDis idibaniswe nesiphelo esinye somqhubi wesiphaluka (umgca wesigaba L okanye umgca ongathathi hlangothi N), kunye nesinye isiphelo somgca wokudibanisa wesixhobo sokumisa izixhobo, ukudibanisa i-equipotential yombane.
