  • Gas-Insulated Substations - GIS

    A gas-insulated substation (GIS) uses a superior dielectric gas, Sulfr hexafluoride, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in Sulfr hexafluoride gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what Sulfr hexafluoride can do in centimeters.

  • Powering the economy Small footprint, high performance

    substation solution becomes attractive. One obvious approach is to use gas-insulated switchgear (GIS), which would occupy only 30,000 m2 for the same SLD as in 1 [1]. This will, how-ever, be more costly than air-insulated substations. According to China State Grid [1], a GIS substation requires around 40 percent higher investment.

  • Sensor - GIS Wiki | The GIS Encyclopedia

    UseClassification of Measurement ErrorsBiological SensorsExternal LinksSensors are used in everyday objects such as touch-sensitive elevator buttons and lamps which dim or brighten by touching the base. There are also innumerable applications for sensors of which most people are never aware. Applications include cars, machines, aerospace, medicine, manufacturing and robotics. sensorsensitivity indicates how much the sensoroutput changes when the measured quantity changes. For instance, if the mercury in a thermometer moves 1 cm when the temperature changes by 1 °C, the sensitivity is 1 cm/°C. Sensors that measure very small changes must have very high sensitivities. Sensors also have an impact on what they measure; for instance, a room temperature thermometer inserted into a hot cup of liquid cools the liquid while the liquid heats the thermometer. Sensors need to be designed to have a small effect on what is measured, making the sensor smaller often improves this and may introduce other advantages. Technological progress allows more and more sen...
