Understand CT is a voltage step up transformer.
HT side has higher voltage but low current.
LT side has lower voltage but high current.
So for CT of rating 500/1 Amps, 500 Amps side(Primary of CT) has very low voltage and 1 Amp side (Secondary of (CT)
has very high voltage(Insane value in KVs).
This high voltage is beyond the maximum impulse withstand voltage of the CT and it blasts the CT. Hence secondary is always short circuited.
Current and voltage are inversely proportional.
