  In this note we study T-duality transformations for the NS5-brane and its
orbifolds along angular directions. We identify a geometric charge for these
configurations and show that it is interchanged with the H-flux under
T-duality. We furthermore perform a supersymmetry analysis and find that
T-duality can break supersymmetry, in agreement with earlier results in the
literature.
  We contrast our findings to compactifications of the NS5-brane on tori, which
have vanishing geometric charge and for which T-duality transformations along
the compact directions preserve supersymmetry. This shows that the
uncompactified NS5-brane and the compactified-and-smeared solution have
different properties and behave differently under T-duality.
