Electronic system for remote identification of the phases of electrical networks and electrical power supply and distribution lines, under voltage

摘要

Electronic system for identifying at a distance the phases of an electrical network, composed essentially of two electronic devices communicating with each other by means of radio transmission or, more particularly, transceiver devices. The system identifies the phases by comparing at any given distance, in real-time, by means of radio frequency transmission, the synchronism or phase angle of the alternating voltages detected at two points of the network. The identification involves the phases of three-phase or multiphase electrical systems alternating at any given industrial frequency, and it is normally done on electrical distribution networks under voltage, at a particular nominal operating voltage and with any given complexity of tapping and transforming nodes. Or the system can basically identify, between two points of a three-phase electrical network under voltage, at any given distance between them, the coincidence of the phases and, thus, an identification of their corresponding conductors.
