Jd. Huddleston et al., A SURVEY OF OPTICAL CHANNELS FOR PROTECTIVE RELAYING PRACTICES AND EXPERIENCE, IEEE transactions on power delivery, 10(2), 1995, pp. 647-658
The Optical Channels for Protective Relaying Working Group of the IEEE
Power System Relaying Committee performed a survey of industry practi
ces for applying optical channels, both planned and installed, for pro
tective relaying communications. This report summarizes the sizes of t
he present and planned optical fiber network, the types of constructio
n, whether the relaying channels are on dedicated fiber or multiplexed
with other ser vices, experience, and maintenance practices.
