Why CT secondary is grounded?

Answer Posted / m p

Ct is the stepdown Former, so in primary 220 Kv means we step downing time the voltage ⚡ is infinite, and current is 1 or 5 amps. so ct secondary short means the voltage ⚡ is zero.while the ct secondary is open means the voltage ⚡ is increasing gradually. And suddenly it goes high, then the insulation of ct is failured, then the ct windings are goes to short circuit conditions. At last the ct is borne.

I have a relay contact rated at 220v dc which is supplied with a 24vdc from the panel,for it to trip the dampers(24vdc).What if the application of the relay changes so that it should work at its rated 220vdc then will it work at 24vdc supply given or any other consideration needs to be taken .....
