Answer Posted / the electrical genius
In case of C.T., if higher value of current will flow, the C.T. core will saturate and so not high current will flow in its secondary. Thus, no use of fuse in this case.
While in case of voltmeter, the resistance of voltmeter is very very high and it limits the current flowing through it in the range of mA. So use of fuse in that case is also not needed !
