The electrical breakdown processes in heterogeneous resistor networks were studied for the case of the time-reversible damage or recealing of resistors. The periodical changes in a damage degree and a total conductivity of a lattice were observed that depend on recealing time constant $τ$ and value of external voltage. The periodical behaviour is characteristic for a pure deterministic breakdown model with recealing and reflect temporally-dimentional changes in the structure of correlated clusters of breakdown resistors. This behaviour can be supressed at increasing external voltage or when the stochastic factor in a damage law is present.
