System DECTRO

Our solution, system "DECTRO"

System "DECTRO" is a device of high voltage overhead power lines. Its for any kind of vehicle which have a metallic part that can touch accidentally a high voltage electric line. Around a line, the device start a visual and audible alarm and block the boom movement in stop it. This one will are unblock by the use people, after he found line (DANGER) and with his responsability. Sensitivity of the device was adapted to a detection of the overhead electric lines 20000 volts, in indicate a presence of a high voltage line in vehicle environement.

Mean of prevention

Used like a mean of prevention, the device prevent use people that a high voltage overhead electric line is near, but it never allow dangerous interventions around electric lines. It doesn't shield user to the rule currently.
(décret 2008-244 du 7 Mars 2008 - obligations du code du travail - article R4534-108).  

Limitated uses

A partial or total mitigation of sensor sensitivity is remarked:                                               - in vertical of a high voltage line in horizontal layer.                             - according to environement of antenna: tree or branches,metallic parts which hidde partially the antenna of line.                   - in hard climatics conditions: snow, frost...                                             SYSTEME DOESN'T DETECT 220v-380v AND DOESN'T FOUND PRESENCE OF CONTINUOUS TENSIONS. Example: 1500 volts (DC) on some power lines like SNCF and 750 volts (DC) for tramway lines that device DECTRO doesn't detect.
