Lus piav qhia luv luv:

1. Daim ntawv thov: Rau kev tiv thaiv cables thiab equipments tiv thaiv overload thiab luv luv Circuit Court.

2. Cov kev cai dav dav rau xaiv MCB.

ib. Cov ntaub ntawv kev lag luam ntawm lub network ntawm lub ntsiab lus tau txiav txim siab: Lub tshuab hluav taws xob hauv ntiaj teb, luv luv tam sim no ntawm Circuit Court breaker installation point, uas yuav tsum tau tsawg dua li qhov muaj peev xwm tawg ntawm cov cuab yeej no, network ib txwm voltage.

b. Muaj 3 tus yam ntxwv nkhaus rau kev ua haujlwm sib nqus: B nkhaus (3-5 Hauv) kev tiv thaiv thiab kev tswj xyuas cov kab hluav taws xob tiv thaiv ntev hauv TN thiab IT systems.

c. nkhaus (5-10 Nyob rau hauv) kev tiv thaiv thiab kev tswj ntawm circuits tiv thaiv overloads thiab luv-circuits; kev tiv thaiv rau resistive thiab inductive loads nrog tsawg inrush tam sim no.

Dcurve (10-20 Nyob rau hauv) tiv thaiv thiab tswj cov circuits tiv thaiv overloads thiab luv-circuits; Kev tiv thaiv rau cov khoom siv hluav taws xob uas muab cov khoom ntim nrog lub siab inrush tam sim no ntawm Circuit Court kaw (LV / LV transformers, tawg teeb).
