Abstract: A method for sectioning a medium-voltage distribution electric line evidencing a disturbance using a section switch. The steps are: (a) detecting a current having an amplitude and a wave form profile in the medium-voltage line; (b) analyzing the wave form profile to determine whether the fault is transient, permanent, a transformer input current or transformer in-rush current; (c) and determining the behavior of the section switch from the result of the wave form profile analysis. The section switch is installed on auxiliary branches of a distribution network having a main line that is protected by an automatic reset circuit breaker. The section switch has an opening mechanism having a coil and an electronic circuit. The electronic circuit has a power source for the coil and electronic circuit, a detector to detect current and an analyzer to determine whether the detected current is a transient or a permanent fault.

Abstract: An apparatus for providing power for transmitting relaying signals from an extra high voltage transmission line to ground potential which avoids the use of a high cost current transformer and which is immediately effective to provide such signals when the transmission line is initially energized to protect such line if it is energized when a fault is present. The apparatus supplies the power from ground potential to line potential by means of sonic quantity transmitted from a first transducer to a second transducer through an elongated rod-like insulating member which preferably is caused to vibrate at its resonant frequency.

Abstract: The present invention discloses a method for sectioning a medium-voltage distribution electric line evidencing a disturbance, wherein said method comprises the stages of: (a) evaluating a current in a medium-voltage line with a detection coil; (b) converting the intensity generated by said current by the detection coil in a potential difference, further transferring the information to a microprocessor; (c) analyzing the profile of the wave generated by the current by an algorithm to analyze harmonic levels by Fourier Series, and (d) determining the behavior or the section switch from the result obtained in (c). Step d) comprises making no count to trigger the disconnection mechanism (i) when the current value does not exceed a predetermined value for which said current is detected as a fault current; (ii) when el the wave profile corresponds to a transformer input current or in-rush current; or (iii) making a count to trigger the disconnection mechanism when the wave profile corresponds to a short-circuit exceeding the predetermined current value as fault current. Given the case of d) (ii) the method further comprises step e) comprising: (i) not triggering the disconnection mechanism when a transient fault is involved; or either, (ii) triggering the disconnection mechanism when the predetermined count number is reached. The method can simultaneously with e) ii) further comprise f) sending a RF signal to other or others parallel connected section switches at a point of the distribution line in order to be jointly disconnected. The invention also refers to section switches for electric power distribution lines for auxiliary branches where the main fine is protected by an automatic reset circuit breaker, which comprises an electronic circuit with a microcontroller capable of distinguishing a permanent fault current from a transient fault current, thereby immunizing the section switch against “in-rush” currents; and to said electronic circuit.
