FAQ

C0, C1, C2 mein ant kya hai? (IEEE C37.06)
IEEE C37.06 capacitor bank switching ke dauran OUTRUSH current kshamata ke aadhar par switchgear ko vibhajan karta hai. C0 (standard): I_o < min(50kA, 1.41 x I_sc). C1/C2: I_o < 2.6 x I_sc, >=15% marjin ke saath. C0 default hai jab tak制造商 dokjar nahi milta.
Surge arrester TOV ghatna se kaise suraksha karta hai?
MOV arresters (metal-oxide varistor) surge energy ko ground mein shunt karke TOV ko clamp karte hain. MCOV woh RMS voltage hai jo arrester liptra sahmta hai — isamen margin ke saath system voltage se upar hona chahiye. TOV kshamata (kV) batati hai ki arrester kitni dhoomachalak anusahan sahan kar sakta hai bina fail huye.
Kab capacitor bank switching event chhod diye jaate hain?
Capacitor bank switching sections (inrush, restrike, energization TOV) automatic roop se chhod diye jaate hain jab 'No capacitor bank' chunna hota hai. bache hue checks (MCOV/TOV, breaker opening energy, 1LG fault, outrush) hamesha chalate hain.
TLI anudesha flag hone par kya karein?
TLI flag ka matlab hai ki OUTRUSH current breaker vibhajan ki rating se upar hai. karya: (1) upstream transformer impedance satyapan karein, (2) current-limiting reactor jodein, (3) capacitor bank ko unchai source impedance waali jagah par daalein, (4) breaker ko upar ki vibhajan (C1/C2) mein upgrade karein.
