Answer / monojit dutta
IF A LOAD IS CONNECTED WHICH WILL DRAW 26 A AT 24 v (i.e
the load value is 24/26=0.92 ohm), THEN THE BACK UP TIME
WILL BE 1 HRS.

Answer / k.prakashchandra
The effective AH will be 26 AH at 24 Volts.Stored energy
will be 26 X 24 watt hours.Divide this by load in watt to
get the back-up time in hours

Answer / sathya
2 battery voltage is in series =24v,
so,P=VxI,the power = 624 watts, it means if u r conecting
624 w load with 24 volt,the voltage and current should be
same for 1 hour,(24v & 26A)depend upon the connecting load
the backup time will be increase r decrease is it correct
let me know pl

I am abt to give IOCL intrv.Plz sir guide me for IOCL intrvw (Electrical).Which subject to be consider. questions are generally asked from which subject.Plz help me out.
1 “earthing” for bonding of equipment and circuits to common plant earth electrode potential, 2 “protective earthing (PE)” when this bonding is required for personal safety provisions 3 “grounding” for interference suppressing bonding of screens, sys-tems with ground level 4. low-impedance earthing ? 5.primary earthing system and secondary earthing system what is that? 6.earthing electrode or mesh net earthing electrode ? very confusing , simple but very informative help required ? i will be very very thankful to you guys.
Practical condition in 400KV Sub station:- Breaker(open) , isolator(open), Earthing (close) at both end e.g A & B. Now Open A Stn Earthing than Open B stn Earthing (Which have a 50MVA reactor) , AND suddenly show R,Y,B phase 704KV,573KV,118KV respectively. Que is without closing of breaker how it is possible.???? My Whats app No:07621840498 for Further Discussion. Pls experts suggest.
