Electric Power Systems Partnership | Fluorinated Gas

Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for insulating gas, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950’s, the U.S. electric power industry has used Sulfr hexafluoridein circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect insulating gas emissions from electric power systems, such as the type and age of the insulating gas-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of sf6 gas, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities. Because of its long life span and high global warming potential (GWP), even a relatively small amount of sf6 gascan impact the climate. The electric power industry uses roughly 80 percent of all insulating gas produced worldwide. Ideally, none of this gas would b...Get price

Sulfur hexafluoride circuit breaker - Wikipedia

Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, Sulfr hexafluoride circuit breakers are widGet price

Pressure Gauges Selection Guide | Engineering360

TypesSpecificationsSensor TechnologyMediaFeaturesDifferential pressureis measured by reading the difference between the inputs of two or more pressure levels. The sensor must have two separate pressure ports; the higher of the two pressures is applied through the high port and the lower through the low port. It is commonly measured in units of pounds per square inch. An example of a differential pressure sensor is a filter monitor; when the filter starts to clog the flow resistance and therefore the pressure drop across the filter will increase. Absolute pressuresensors measure the pressure of a system relative to a perfect vacuum. These sensors incorporate elements which are completely evacuated and sealed which serve as the vacuum reference. Input pressure is applied through a single port. Gauge sensors are the most common type of pressure sensor. The pressure is measured relative to ambient pressure which is the atmospheric pressure at a given location. The average atmospheric pressure at sea level is 1013.25 mbar but changes i...Get price
