Invention patent for a device provided with at least two charge electrodes (3 and 4), which are aligned vertically, adjacent to at least one discharge electrode (9), mounted on a pin (10), which conducts to an earthed line (11); said device is provided with a varistor (17) connected to the phase line via the phase charge electrode (1 to 3) and neutral charge electrode (4) and to the discharge electrodes (12 to 15) of earth (11), having an LED (20) connected to the varistor (17), at the positive terminal thereof, for identifying a situation of electrical connection of the system and integrity of the varistor (17), having the negative terminal connected to the neutral; a means of regulation of the arresting of the spark of an overvoltage consists in the transfer between the charge electrodes (1, 2, 3 or 4) and discharge electrodes (12 to 15) and a method for detection of leaks of small transients is obtained by means of the leaking current being diverted to a device of the varistor (17) type that, when the actuating voltage has been exceeded, heats and overcharges the LED (20), burning out the latter, thereby providing an alert that there has been a leak of electrical current and a need for adjustment among or replacement of the electrodes (1 and 12 or 2 and 13 or 3 and 14 or 4 and 15), and redirects the transient to earth, thereby protecting the electrical network. |
