%0 Journal Article %T Novel Method for Current Measurement using Single Mode Fiber %A Ghanshyam Kumar Singh %A Ganapathy Krishnamurthy %J International Journal of Engineering Sciences & Research Technology %D 2013 %I %X This paper presents a Fiber optic current sensor (FOCS) which employs selected cut-off single mode fiber. It is all-glass fiber supporting single mode light propagation for operating wavelength of 633 nm from the HeNe laser. A simple and modified practical setup to measure the current, based on the Faraday¡¯s Effect is proposed. Experimental results are analyzed and a new formula has been obtained to measure the current using this practical setup. %K Fiber Optic Current Sensor %K Faraday Effect %K Single mode fiber %K current measurement. %U http://ijesrt.com/issues%20pdf%20file/Archives%202013/august-2013/20.pdf
