Answer / subash konar

Density with respect to water.If it decreases efficiency of
battery becomes low thereby decreasing current and voltage.

Answer / harish kuqhsal

SPECIFIC GRAVITY OF A BATTERY IS THE ENERGY DERIVED PER UNIT
WEIGHT OF THE CELL. WITH THIS THE VOLTAGE AND CURRENT IS NOT
AFFECTED.

Answer / manoranjan

Specific gravity is the ratio of the weight of a solution to
the weight of an equal volume of water at a specified
temperature. Specific gravity is used as an indicator of the
state of charge of a cell or battery. However, specific
gravity measurements cannot determine a battery's capacity.
During discharge, the specific gravity decreases linearly
with the ampere-hours discharged.
so specific gravity depends on volage/current.

Answer / vinod

its change with the cherge or discharge the battery.

Answer / vishal ingle

It is an indication about the charge storing capacity of a
battery. If sp. gr. decreases / increases, it affects the
voltage across terminals merely but the back up provided
will be affected adversely. In simple words, the battery
performs optimally near to the standard sp gr of 1200.

3 Answers   Hosco,

Dear Friends, I have a 500KVA transformer supplying whole factory having 3 phase and single phase mixed loads. Power room has ammeters connected via CTs for individual phase. Now I know that readings shown on meter for each phase say R,Y and B are line currents. But when I want to know the total on transformer do I need to add the currents of all three phases readings shown on meter or value for anyone phase will give me the correct power load on transformer for that point of time. 2. If ammeter shows unbalanced readings for R,Y, B phases say 150, 250 and 300 respectively so can I assume that 150A i.e average of 3 will be the 3phase load currents and remaining will be 1phase currents. Please clarify my doubt.
