Fault location and control system for distribution lines
First Claim
1. A fault location and control system for a distribution system comprising:
- a central computer connected at one end of the distribution line;
at least one casing adapted to be installed at various locations along the distribution line, each casing enclosing;
a radio transceiver; and
an amplitude modulation detector connected to the radio transceiver;
wherein each casing is installed a predetermined distance from each other;
wherein when a fault is produced in the distribution line, each one of the amplitude modulation detectors adjacent to a place where the fault is produced, emits a signal; and
wherein the central computer detects and compares the location of the place where the fault is produced by comparing the time of arrival of the signals.

Abstract
A location and control system automatically locates, identifies, and corrects faults on a distribution system. The fault location and control system includes a central computer connected at one end of the distribution network and one casing installed at various locations along the distribution network. Each casing encloses a radio transceiver, plus an amplitude modulation detector connected to the radio transceiver. Each casing is installed at a predetermined distance from each other. When a fault is produced in the distribution line, each of the amplitude modulation detectors adjacent to a place where the fault is produced emits a signal that is detected by the central computer. The central computer detects and compares the location of the place where the fault is produced by comparing the time of arrival of the signals. The central computer may then automatically or manually disconnect any part of the distribution network in order to extinguish the fault arc.

8. A method for detecting a fault on a distribution line, the method comprising the steps of:
-
connecting a central computer to one end of the distribution network; installing a casing at various locations along the distribution line, wherein each casing encloses a radio transceiver and an amplitude modulation detector connected to the radio transceiver; wherein when a fault is produced in the distribution line, each one of the amplitude modulation detectors adjacent to a place where the fault is produced, emits a signal; wherein the central computer detects and computes the location of the place where the fault is produced by comparing the time of arrival of the signals; and wherein the central computer may automatically or manually disconnect part of the distribution network to extinguish the fault arc and reduce the probability of fire.
