Abstract

L'apparecchiatura comprende dispositivi capacitivi accoppiati ai conduttori elettrici, che emettono correnti alternate a bassissimo amperaggio. Tali correnti vengono utilizzate da circuiti rivelatori di tensione e da circuiti rivelatori di fase associati ad ogni conduttore, i quali forniscono un impulso luminoso ad ogni n periodi e rispettivamente ad ogni periodo di dette correnti alternate. Le due serie di impulsi vengono poi trasferite mediante cavi a fibre ottiche in una posizione accessibile a distanza di sicurezza, dove la prima viene utilizzata direttamente, per verificare visivamente la presenza di tensione sul conduttore, e la seconda viene utilizzata indirettamente, tramite un dispositivo comparatore di fase, per verificarne lo sfasamento rispetto ad un'analoga serie di impulsi relativi ad un altro conduttore.
