  In these proceedings we present preliminary $\pi^{+}\pi^{-}$
electroproduction cross sections off protons in the kinematical area of 1.4 GeV
$< W <$ 1.8 GeV and 0.4 GeV$^{2}$ $< Q^{2} < 1.1$ GeV$^{2}$. Our results extend
the kinematical coverage for this exclusive channel with respect to previous
measurements. Furthermore, the $\pi^{+}\pi^{-}$ electroproduction cross
sections were obtained for $Q^2$-bins of much smaller size. The future analysis
of this data within the framework of the JLAB-MSU reaction model (JM) will
considerably improve our knowledge on the $Q^2$ evolution of the transition
$\gamma_{v}NN^*$ electrocouplings, in particular for the resonances with masses
above 1.6 GeV.
