Single-pole voltage detector, in particular for overhead electrical lines |
摘要 |
A voltage detector includes, inside a Faraday cage, between a contact electrode and a counterweight outside the Faraday cage, a load resistor to which is connected a detector circuit driving at least one indicator device. The distance L between the counterweight and the contact electrode and the active surface area S of the counterweight respectively and simultaneously satisfy the following conditions: L>200 mm 50 mm2<S<500 mm2. The counterweight includes a conductive wire that is part of a screened electric cable. The screen is shorter than the electric cable and is a tubular extension of the Faraday cage. Applications include testing overhead transmission and distribution of electric wire lines.
