instead of dc
|why transformer ratings in kva?
|when we are going to higher voltage level in substations why

the C.T will sense the current in only one direction.
|why fuse is not applicable for nutral and what will happen
when it applied.
|On wat basis TSM & PSM are set? Example.TSM=30% n
PSM=2.5A....Hw they are set and how we come to know that
the particular relay should be set to this value only?
|Why we apply only reduced voltage to the alternator while
conducting slip test ? also the current increases to a
larger value with reduced voltage itself Why ?
|why we are connecting the alternator to a steam turbine of
higher RPM then the rated RPM of alternator?
For example:( connecting 1500 rpm alternator to 7600 rpm
steam turbine). we can directly connect the same rpm
turbine to alternator know??? is there any special reason ???
