Why we connect the capacitor in Delta?if we conect in Star
what will happen?

Answer Posted / t. eswara rao

Capacitors are used for compensating the inductive reactive
power in the system and bring the power factor to the unity.
But the question is what is problem if we connect them in star?
If we connect them in star , and any capacitor fails ,
it momentarily shorts the supply voltage and raises the
voltage levels across the remaining capacitor banks
connected in the remaining phases. This may lead to destroy
the other two capacitor banks also.
