Abstract

Sensor de voltaje de fibra óptica codificado en frecuencia, para redes de corriente alterna, que se caracteriza porque, utilizando fibra óptica monomodo, el voltaje aplicado genera una señal óptica cuya intensidad está modulada en frecuencia. La modulación en frecuencia codifica la amplitud y la forma de onda del voltaje aplicado. El sistema consta de una fuente de luz coherente de onda continua, que alimenta un interferómetro de fibra óptica, un elemento sensor dispuesto en el interferómetro y un fotodiodo transductor potencia óptica/voltaje. El circuito óptico es un interferómetro de fibra óptica, pero no constituye un sensor interferométrico (ni de fase) convencional, ni requiere compensación de deriva alguna, dados el diseño y forma de operación que se emplean. De aplicación en el transporte y distribución de electricidad.Frequency coded fiber optic voltage sensor, for alternating current networks, characterized in that, using single mode optical fiber, the applied voltage generates an optical signal whose intensity is frequency modulated. Frequency modulation encodes the amplitude and waveform of the applied voltage. The system consists of a coherent continuous wave light source, which feeds a fiber optic interferometer, a sensor element arranged in the interferometer and a photodiode optical power / voltage transducer. The optical circuit is a fiber optic interferometer, but it does not constitute a conventional interferometric (or phase) sensor, nor does it require any drift compensation, given the design and method of operation used. Of application in the transport and distribution of electricity.
