The scope of this guide is to furnish an understanding of the conditions that generate gases in paper and laminated paper-polypropylene insulated fluid-filled cable systems; to establish a recommended method for sampling, data collection, analysis; and to identify possible remedial actions for systems with high dissolved gas-in-fluid content. This guide is intended to provide users of pipe-type cable systems, both high-pressure fluid-filled (HPFF) and high-pressure gas-filled (HPGF), as well as self-contained fluid-filled (SCFF) cable systems with the basis to establish the use of gas-in-fluid analysis for diagnostic purposes, part of condition assessment, and as a maintenance tool. Revision Standard - Active. The application of the analysis of gases dissolved in the fluids of fluid-filled cable systems is discussed in this standard with respect to the procedures for sampling, obtaining the dissolved gas data, and analyzing the results.
