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

Differnce between acb and vcb

Answer / nagaraju. s

Vcb it's a closed circuit, it's a vacuum circuit breaker , it's used high voltage

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

I am new guy as an electrical engr. in a 100MW HFO based power project. I am in operations division. I have noticed from last few days, my supervisor sends the last 24 hours energy generation calculation to my plant manager. I have noticed, he calculated last 24 hour's generated energy differences in KWH then he multiplied it with a multiplying factor 960. for example: total difference =2.685 KWH*960= 2577.6 MWH. but he does not not know what is multiplying factor 960?? can anybody explain it??
