VOLTAGE DETECTING SYSTEM

This VDS, Voltage detecting system according to IEC 61243-5, is based on the sharing of voltage between capacitor C1 (high voltage) and capacitor C2 (low voltage); the signal at C2 terminals is transformed in an optical signal, which separately points out voltage and phase of the line involved.
Thanks to this new system the signals of voltage get to the operator through a galvanic (optical) insulation, which never transfers voltage, even in case of failure of capacitor C1.
