Base station - GIS Wiki | The GIS Encyclopedia

Land SurveyingComputer NetworkingWireless CommunicationsGallerySee AlsoReferencesIn the context of external land surveying, a base station is a GPSreceiver at an accurately-known fixed location which is used to derive correction information for nearby portable GPS receivers. This correction data allows propagation and other effects to be corrected out of the position data obtained by the mobile stations, which gives greatly increased location precision and accuracy over the results obtained by uncorrected GPS receivers.Get price

Electrical substation - Wikipedia

A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions.

5 Differences Between Air-Insulated Substations and Gas

ConstructionInstallationOperationMaintenanceTotal Cost of OwnershipGIS high voltage substationengineering uses the gas sulfur hexafluoride for insulation, whereas AIS uses air insulation in a metal-clad system. Sulfur hexafluoride is five times heavier than air and offers excellent extinction behavior. Another significant construction-based difference between the two switchyards is that a metal-clad AIS uses three-position draw-out circuit breakers (on, off and test). GIS systems use fixed, mounted circuit breakers. The sealed mounted breakers are a ‘sealed-for-life’ technology, whereas the AIS breaker can be removed for maintenance and troubleshooting.Get price
