in an acb the distance between terminals are fixed for 415
volts. for higher voltages this need to be much larger.
there are some makes acbs are available in 3.3 kv with
increased gap to the tune of 2 feet. For higher voltages the
gap required will be very much higher.arc handling will be
impossible in higher voltages

any one can explain the stages of a knee point which is taken during ct magnetising curve.

3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
