sensor detector of presence - absence of alternating voltage, hindu and capacitiva in air to compartments of electric lines of the distribution

摘要

the sensor is composed of a plate material captatrice elettroconduttivo or resistivo, from a plate material elettroconduttivo screen.superimposed on first with interposed insulating material, from a piece of wire with stocking of screen that connects the plates to the unit amplificatrice electronic signal which final stage.the sensor detects the presence and absence of alternating voltage, current on conductors of power lines, mainly in electrical distribution panels in voltagewithout any direct contact with the conductors.the sensor placed at a safe distance from the conductor under tension, with the plate captatrice directed towards the same and the plate screen connected to the ground potential.it is able to detect for inductive effect capacitivo in air or via dielectric, a signal of alternating voltage of a few mv.appropriately amplified by an electronic unit, signal the presence of voltage on the conductor concerned.
