Evaluation of Gradient Control Wire and Insulating Joints as Methods of Mitigating Induced Voltages in Gas Pipelines
Significant voltage levels can be induced in the gas pipelines due to power transmission lines in the areas where they share the same corridor, especially during a fault. These voltages can affect the operating personnel, pipeline associated equipment, cathodic protection and the pipeline itself. Quite often, mitigation is required to reduce these induced voltages to levels that are safe for pe...
متن کاملProperties of Mineral Insulating Oils in Service
The infrastructure of the electricity grid and super grid system in the hitherto industrialized world was to a large extent built up in the decades following World War II with a peak in investments around 1960-1980. This means that the flotilla of power transformers is now starting to reach projected lifetime of around 40 years. During the last couple of decades there has also been an ongoin...

متن کاملMODELING OF ASPHALTENE DEPOSITION IN PIPELINES
This paper is concerned with asphaltene deposition in fluid flowing through pipelines. Brownian diffusion and drag, gravitational, thermophoresis, buoyancy, and shear removal are considered as possible mechanisms in the asphaltene deposition process. The thermo-physical properties of the fluid were obtained from Iranian oil fields. A model was used in the pipeline deposition modeling to predict...
متن کاملMinimizing Uncertainty in Pipelines
In this paper, we consider the problem of debugging large pipelines by human labeling. We represent the execution of a pipeline using a directed acyclic graph of AND and OR nodes, where each node represents a data item produced by some operator in the pipeline. We assume that each operator assigns a confidence to each of its output data. We want to reduce the uncertainty in the output by issuin...
