Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

SF Maintenance Equipment Fundamentals

As a hybrid of the high-pressure and refrigeration process, heat-exchanged systems rely on a series of forced-air coolers to extract heat from the compressed SF 6. As a benefit of reduced temperatures and pressures, this approach allows gas to be liquefied at a slightly faster rate than the direct high-pressure approach.Get price

Landing AI Creates an AI Tool to Help Customers Monitor

CalibrationDetectionMeasurementAs the input video may be taken from an arbitrary perspective view, the first step of the pipeline is computing the transform (more specifically, the homography) that morphs the perspective view into a bird’s-eye (top-down) view. We term this process calibration. As the input frames are monocular (taken from a single camera), the simplest calibration method involves selecting four points in the perspective view and mapping them to the corners of a rectangle in the bird’s-eye view. This assumes that every person is standing on the same flat ground plane. From this mapping, we can derive a transformation that can be applied to the entire perspective image. This method, while well-known, can be tricky to apply correctly. As such, we have built a lightweight tool that enables even non-technical users to calibrate the system in real time. During the calibration step, we also estimate the scale factor of the bird’s eye view, e.g. how many pixels correspond to 6 feet in real life.Get price
