Calaamadaha Loo Baahan Yahay
Ka dib Markii la Helay Shahaadada UL, soo saaruhu wuxuu qaadayaa mas'uuliyadda inuu la kulmo heerarka si dhab ah. Dhammaan SPDs waxaa ku jira calaamado cad oo joogto ah oo loo baahan yahay si loo hubiyo xalalka aad dooratid inay la kulmaan UL 1449.
- Magaca soo saaraha
- Lambarka Catalogga
- Nooca SPD
- Qiimeynta korantada
- Qiimeynta dheecaanka magacaaban ee hadda (In)
- Ugu badnaan heerka qiimeynta danab ee hawlgalka (MCOV)
- Qiyaasta ilaalinta danab (VPR)
- Cabbiraadda xaddidan xaddidan (MLV)
- Taariikhda ama muddada wax soo saar
- Wareeg gaaban oo hadda socda (SSCR)
Nooca 4 goleyaasha qaybaha iyo Nooca 5 SPDs waxay u baahan yihiin MLV, MCOV, danab shaqeynaya, iyo Qiimeynno. Nooca 5 SPDs qiimeyntan waxaa lagu bixin karaa xaashiyaha xogta.
Qaamuuska ereyada muhiimka ah
- Cilad hadda - Xilliga laga joogo nidaamka tamarta ee ku socda wareegga gaaban
- Ugu badnaan danab hawlgal joogto ah (MCOV) - Qaddarka ugu badan ee danab ee si joogto ah loogu dabaqi karo SPD
- Cabbiraadda danab xaddidan - Baaxadda ugu badan ee danab ee la cabiro marka In la adeegsado
- Dheecaan aan caadi ahayn oo hadda socda (In) - Qiimaha ugu sarreeya ee hadda (8 x 20 qaab muuqaal ah) oo lagu dhex maro SPD 15 jeer (SPD waa inuu sii ahaadaa mid shaqeynaya)
- Danab hawlgal magaceed - Awoodda caadiga ah ee korantada AC ee nidaamka
- Awoodda magaceed (Vn) - Danab DC oo lagu cabbiro guud ahaan SPD marka 1mA ay socoto
- Gawaarida Gawaarida Gaaban ee Gaaban (SCCR) - Ku habboonaanta SPD si ay ugu adkeysato wareeg gaaban oo laga soo sheegayo isha korantada
- Qiyaasta ilaalinta danab (VPR) - Qiimeynta danab ee laga soo xulay liiska qiimaha la doorbiday markii la isku daro mowjad isku dhafan oo ah 6kV 3kA
