Abstract: In the estimation of the circuit breakers technical state, it is very important to knows its contacts electroerosion. The electroerosion depends on the following main parameters: switching number realised, currents values that have been switched, existence time of electric arc at each switching. Electroerosion estimation of the contacts realised in operation leads to an overestimation inducing a supplementary maintenance. Thus it is necessary an evaluation of short-circuit currents in the mounting place of circuit breakers from electrical installations and a reconsideration of switching number at short-circuit of its. In this paper is shown an experimental model of an embedded intelligent system for the technical state evaluation of the switchgears contacts, from electroerosion point of view. This approach has the advantage that the architecture can be used, also, for the monitoring of the some cinematic parameters for the operating mechanism, like as: closing/open!
ing velocity, closing/opening time, the stored energy in the operating mechanism and others.
