Answer / ajit salunkhe

its Each cell volatge is about 2.2v & specific gravity is
about 1250

Answer / engineering.force

u can check if a battery is fully charged or not by
measuring its specific gravity and comparing it with the
manufacturer's data sheet mentioned specific gravity when
fully charged. if they are equal means that the battery is
fully charged. if not, the battery is not fully charged. the
above answer is battery specific, i.e. depends on what kind
of battery is used in what kind of application. the above
mentioned batteries are generally used in the sub-stations
or LDC's for the the power supply back-up or to operate the
CB's in case of ac power failure, or to act as back-up power
supply for the SCADA/PLC etc.

I have connected 04nos. earthings to a transformer through 04nos. earthing pits seperately. 02nos. earthings are connected to T/F body, and 02nos. earthings are connected to T/F neutral.T/F capacity is 2000KVA, 11KV/415V. But after completing of 02 years successful operation ,we are facing following problems- 1. CT/PT occured blast one time 2. HT cable box occured blast two times 3. One body earthing strip and one neutral earthing strip of transformer are overlapping at some places. Whenever these two strips are pressed at overlapped points, they made spark. What is the reason of spark? Please explain the reason & rectification of above problems
