Charge fluctuations provide a possible signature for the existence of thede-confined Quark Gluon Plasma phase (QGP). Being sensitive to the square ofthe charges, fluctuations in QGP, with fractionally charged partons, aresignificantly different from those of a hadron gas with unit charged particles.Studies of charge fluctuations have been carried out using the variable,$\nu_{(+-,dyn)}$ which, by its construction, is free from collisional bias(impact parameter fluctuations and fluctuations from the finite number ofcharged particles within the detector acceptance). The dependence of chargefluctuations on the pseudo--rapidity windows for various centrality bins isanalyzed for Pb--Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV in the ALICEexperiment at CERN-LHC. A scaling behavior is observed as a function ofincreasing pseudo-rapidity window for the charge fluctuations, expressed interms of \nchnudyn, where $N_{ch}$ is the number of charged particles. Theresults are compared to experimental measurements at lower energies and tomodel predictions.
