  Voltage operations extend traditional geometric and combinatorial operations
(such as medial, truncation, prism, and pyramid over a polytope) to operations
on maniplexes, maps, polytopes, and hypertopes. In classical operations, the
symmetries of the original object remain in the operated one, but sometimes
additional symmetries are created; the same situation arises with voltage
operations. We characterise the automorphisms of the operated object that are
derived from the original one and use this to bound the number of flag orbits
(under the action of the automorphism group) of the operated object in terms of
the original one. The conditions under which the automorphism group of the
original object is the same as the automorphism group of the operated object
are given. We also look at the cases where there is additional symmetry, which
can be accurately described due to the symmetries of the operation itself.
