Abstract

Abstract:
Electroerosion estimation of the contacts realised in operation leads to an overestimation
inducing a supplementary maintenance. In this paper is shown an architecture with
microcontroller 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 speed, opening speed, closing time, opening time, the energy
accumulated in the acting mechanism and others.
