摘要

Method for switching a line of Medium Voltage presents a disturbance, comprising: (a) evaluate a current with a detector Coil; (b) convert the intensity difference of potentialTransferring information to a Microprocessor; (c) analyse the Wave profile using an algorithm for Harmonic analysis by Fourier series; and (d) determine the behavior of the Switch according to the results obtained in (c).(d) comprises the step: do not make a count if: (i) the current exceeds a preset value as Fault Current, or (ii) The Wave Profile corresponds to a current u00f4in rushu00f6, or (iii) to perform a Count disconnection if the Wave Profile corresponds to a Short Circuit, which Overcomes a V Alor prefixed as Fault current.As (iii), and the method comprises: i) not making the shot Break mechanism if it is a temporary glitch; or (ii) to disconnect if it reaches a Predetermined number of Counts.Additionally, the method may include simultaneously (e) (ii), (f) Send a Signal to other / s RF switches Connected in a parallel line point of distribution to be put together.Switch Electric Power Distribution lines for Auxiliary branches where the Main Line is protected by a Circuit Breaker Automatic replacement, which comprises an electronic circuit with a Microcontroller that can identify Permanent Fault current of a tra Nsitoria DISCONNECTOR, immunizing against u00f4in rushu00f6 flows, and the Electronic Circuit.
