CONTACTLESS VOLTAGE SENSING DEVICES

摘要

A contactless voltage sensing device (100) configured to measure a voltage value of a conductor (102) is provided. The contactless voltage sensing device (100) includes a first impedance element (108) having a first impedance, where the first impedance element (108) is configured to be operatively coupled to the conductor (102). Further, the contactless voltage sensing device (100) includes an antenna (110) operatively coupled to the first impedance element (110), a second impedance element (133) having a second impedance, where the second impedance element (133) is formed in part by the antenna (110) and a parasitic impedance element (118), and where the parasitic impedance element (118) includes a parasitic impedance, and measurement and communication circuitry (132) coupled to the first impedance element to measure the voltage value of the conductor.
