NiCd batteries typically last longer, in terms of number
of charge/discharge cycles, than other rechargeable
batteries, and have faster charge and discharge rates than
lead-acid batteries, with minimal loss of capacity even at
high discharge rates.*The most common alternative to NiCd
batteries are '''[[lead-acid battery|lead-acid
batteries]]'''. Compared to these, NiCd batteries have a
much higher [[energy density]]. This means that, for a
given battery capacity, a NiCd battery is smaller and
lighter than a comparable lead-acid battery. In cases
where size and weight are important considerations (for
example, some transportation applications), NiCd batteries
are preferred over the cheaper lead-acid batteries.

A three phase load, around 4 km away from the 11/0.433KV distribution transformer (Neutral of Transformer is solidily earthed) and consisting of mainly very costly and sensitive electronic equipments is giving trouble due to high voltage difference between neutral and body earth. Whether this problem can addressed by connecting neutral at the load point solidly to earth?

Transmission line design. Say, I have a 1MVA generator and 2 transformers that will have the same load. What would be the proper rating of the trasformers? Is it safe to say, that I will simply divide the total rating of the generator?
