Paper Abstract

Fiber optical systems are becoming increasingly important for measurement of current and voltage in high voltage environments. Conventional electrical wiring such as transmission line for voltage transformers can readily be replaced by noise-free fiber optics. A novel active voltage transformer with an optical data communication link has been demonstrated. The system includes a transducer based on the capacitive divider and two electrically isolated signal conditioning sections with optical fiber communication link. The proposed solution allowed for designing and developing a novel and high-performance voltage transformer for in-field application. A prototype version of the transformer was constructed following the new standard, with digital output interface to protection devices and the experiment results confirmed a 0.2 accuracy class.
