Strong deterrent effects - significant increase of resistance time
A security electric fence is a system that is installed in second level behind the normal fence. It essentiallly consists of detected wires in combination with high voltage pulses without being hazardous to health. The transmitted energy does not exceed 5 Joule despite the high voltage of several thousand volts. It corresponds thereby to the principle of an electric pasture fence.
The configuration of a security electric fence per se is very simple. The live wires are led with a space of ca. 10 cm over insulators that are mounted on an additional bar. This bar again is fixed at the origin fence pole. The height of the electric fence part is about 2.6 m and towers most fences with that about 60 cm. This makes an overclimbing difficult as well.
The system allows a configuration between energy pulses only and/or detection at the location of touching as well. Alarmzones can be configurated by special isolators. The security electric fence has beside the high deterrent effects the advantage to increase the resistance time against entering the PV farm significant. A sabotage is hardly possible.
Energy-wire systems such as the electric security fence are used very often at places where conventional security systems find their limits, because intruders won’t be deterred by the systems or where a high criminal energy is expected.
