Answer Posted / silamparasan p.
Fuse is used to limit overcurrent. So we have to use fuse
in phase only.
Neutal is for pass, if any faulty current or unbalanced
current. We dont know how much Ampere current flows through
the neutral during any fault or unbalance, it may be high
current also. If we use fuse in neutral during faulty
current the fuse in neutral will blown and it will camage
the unbalanced power system. And it will damage yje
components.

In PFI plant one stage capacitor connection is directly connected(with out megnetic contact controll). but why?
in a solar power plant,we are going to step up the voltage 350V to 33kv, and to 132kv GSS. i want to ask that if it is possible that 315v/33kv is not possible because we also use 315v/11kv. or it should be 415v/33kv? is it effects generation or losses? the second question is-generation is depends on LV winding? or LV winding design for generation voltage?
