摘要:
A method of measuring a current of a current carrying cable teaches the first step of providing an optical sensor assembly comprising a base unit, and an optical current sensor mounted on the base unit for transmitting a beam of polarized electromagnetic radiation to an optical fiber. A light detector is also provided having a first channel that operably connecting the light detector to an analog to digital converter through a programmable gain amplifier, a second channel that operably connects the light detector directly to the analog to digital converter, and a processor operably connected to the analog to digital converter. The optical sensor assembly is mounted adjacent the current carrying cable, and the fiber optic is operably connected to a light detector. A plurality of factors are then evaluated from rotation information from the light detector, by using the first and second channels for analog to digital conversion operably connected with the processor.
