SELF-SUPPLIED WIRELESS CURRENT METER FOR USE ON DISTRIBUTION LINE OR DISTRIBUTION NETWORK

摘要

self-powered wireless current meter for use in distribution line or distribution network Technical Sector: Electrical The invention is a measuring instrument capable of measuring effective alternating current, storing a set of measurements and sending it by radio link, for systems capable of reading and recording samples from this set. The meter operates and acquires currents in the range of 2a to 30a on distribution lines or distribution networks with 13.8 kv and 69 kv voltages. Meter power is obtained from the current itself to be measured. The power collected by electromagnetic induction is sufficient to charge a supercapacitor and power the measurement and data transmission circuits.
