摘要:
A current sensing system comprises a current transformer; a burden resistor connected across a secondary of the current transformer; a piezo-optic sensor coupled to the burden resistor, comprising a piezoelectric transducer, an optical fiber and a first optical filter with a first bandwidth; and an optical interrogator, configured for sending an originating signal to the first bandwidth optical filter and receiving a resulting data signal and a second optical filter with a second bandwidth for filtering the resulting data signal.
