发明名称 METHOD FOR CONTROLLING THE OPENING OR CLOSING OF AN ELECTRIC CIRCUIT IN AN ELECTRIC METER
摘要 A method of controlling the opening or the closing of an AC electric circuit in an electricity meter by means of a relay is provided. The method times relay activation commands so as to take account of the inertial delay (di) of the relay, in such a manner that the actual activation command applied to the relay causes the relay actually to take action on the electric circuit when an electrical parameter of said circuit reaches a zero value, in order to limit the formation of electric arcs in the relay.
