KVAR is the reactive power utilised by the generators,
transformers, motors for producing magnetic flux
KW (true power) is the actual power or true power that
performs actual work
KVA ( Apparent power)is the vector summation of KW+KVAR
KVA=KW+KVAR

how we can do the insulation on secondary of ct explain and so that tan delta will within limit
