Guidelines for gas-in-fluids analysis for diagnostic purposes on cable system condition, and as an operation and maintenance tool to determine when corrective action may be reqyuired. Cable system operators are finding it increasingly important to determine potential problems that may be due to overstressed, overheated, mechanically-damaged, or improperly operated cables. Directly monitoring the cable itself is not possible without de-energizing the system and removing a sample for laboratory evaluation Periodic gas-in-fluid analysis can allow the utility to reliably determine cable condition and undertake proper corrective action. New IEEE Standard - Superseded. The application of the analysis of gases dissolved in the fluids of fluid-filled cable systems is discussed with respect to the procedures for sampling, obtaining the dissolved gas data, and analyzing the results.
