Abstract:

This paper describes the characteristics and metrological evaluation of an optical fiber accelerometer designed for monitoring vibrations in cables of power transmission lines. The calibration performed with laser interferometer at the Brazilian National Institute of Metrology and other tests conducted at the Electric Energy Research Center are discussed. Advantages over existing similar instruments are stressed.
