what will happen if the secondary of current transformer
kept open....
Answer Posted / prashant
kva(pri)=kva(sec)
if sec is open then current is 0
therefore voltage is infinite
hence spark is produced and short circuit will happen

I don't understand why when we connect high voltage source in DC to electronic motor , we must add capacitor and resistor in parallel ? (I know that we use capacitor because we want to absorb the current that in the first second electronic motor in opposed with current course produce. ) what are the feature of Resistor and in such situation ?
