Putting the customer in the driver’s seat to plan substation

The GIS is very reliable equipment with a minimal rate of failure, but it is not possible to rule them out completely. With more and more energy transported in even more complex network systems, a major failure can result in feeder lines or in extreme cases complete substations being out of order with the possible consequence of energy black out.Get price

sf 6 decomposition maintenance dilo

Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (insulating gas) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of Sulfr hexafluoride to SOF2, SO2F2 and SO2 and other characteristic component gases.Get price

Understanding Natural Gas Compressor Stations

Components of A Compressor StationPermitting and Regulatory FrameworkSafety ConsiderationsCommunity and Landowner ConsiderationsMunicipal and Zoning ConsiderationsRight of Condemnation Or Eminent DomainExtensionRoleResourcesNatural gas enters a compressor station through station yard piping and is passed through scrubbers and filters to extract any liquids and remove solids or other particulate matter that may be in the gas stream (Figure 1). Once the natural gas stream has been cleaned, it is directed through additional yard piping to individual compressors. Computers regulate the flow and number of units that are needed to handle the scheduled system flow requirements. Most compressor units operate in parallel, with the individual compressor units providing the needed additional pressure before directing the gas back into the pipeline with full operational pressure restored. When the required boost in pressure is very high, several compressor units may be operated in stages (serially) to achieve the desired pressure in stages. As natural gas is compressed, heat is generated and must be dissipated to cool the gas stream before leaving the compressor facility. For every 100 psi increase in pressure, th...Get price
