1. what is difference between VCB and ACB.how its works
please explian.
Answers were Sorted based on User's Feedback
VCB means vacuum circuit breaker it used in high voltage
(HV) lines
It has one mechanism in this mechanism spring is there it
is connected with small electric motor for charging the
spring but we can do manually charge also by this spring
tension circuit closing or circuit open can be done. The
circuit closing can be done by (CC closing coil) also.
In VCB CT are used for measuring, controlling & protection
purpose.
ACB means air circuit breaker it is used in low voltage
(LV) lines
It has also one mechanism it also work same.
ACB has (UV Under voltage) it used for tripping purpose
when power fail.
It has (CC Closing coil) for closing the circuit.
CT are used for measuring, controlling & protection purpose

Answer / n. gopala krishna
difference between vcb and acb. vcb is vacume circuit
breaker acb is air circuit breaker . in vcb switching
contacts fixed in vacume cylender. in acb switching
contacts arranging in openly in airbut other all mechanisim
is same both breakers having closing coil and tripping coil
and spring charge motor all are having but vcb breakers
using in high voltage side to reduse the arc at on off
time. but acb can use in low voltage side only

Answer / anil kumar
Sorry all
CT are use the low voltage line
CT not use high voltage line We are use the pt in the high voltage
