3. KTP ni tanlash
Hamma obektlarda to’la quvvat topilgandan so’ng umumiy quvvat kataligiga qarab KTp sonni tanlanadi va shahar istemolchilari 2 toifa bo’lgani uchun ularda yuklanish “0.85” dan oshmasligi kerak.
KTP soni
Agar S_n<10000 kva bo’sa 2 ta KTP
10500 kvan<15500 kva 3 ta KTP
16000 kva< S_n bo’lsa 4 ta KTP tanlashimiz zarur
Variant bo’yicha to’la quvvat 5877.5 kva bo’lgani uchun 2ta komplekt trasformator podstasiya tanlaymiz

KTP qurish joyini aniqlash uchun KTP1 istemolchilar markazini aniqlab olamiz

X₀ = Σ(P_ri ∙ X_i) / ΣP_pi
Y₀ = Σ(P_ri ∙ Y_i) / ΣP_pi
Bu yerda ΣP_pi KTP1 istemolchilarini aktiv quvvatlari yig’indisi
X₀=(150*2.6+304.1*6+304.1*9+8.7*357.6+70*6+6*9.5+330*15.5+ 1605*2.7)/(3126)=3.1 sm
