Land Information System LIS is defined as the geographic information system for land-use and cadastral mapping. On the other hand.


Differences Between Ais Gis By Mahmoud Abdelfatah

Also Land information System entails data which are used for legal boundaries of land tenure.

Difference between ais and gis ppt. Conductors also need phase to phase insulation In SF6 GIS these insulation requirements are met by cast resin insulators and SF6 gas insulation. On the other hand remote sensing is the science of collecting data regarding an object or a phenomenon without any physical contact. GIS equipment offers a smaller footprint and space savings but may have higher initial cost.

Initial cost of GIS is higher by about 50 than AIS but when the cost of land is considered in capital cost the overall capital cost is comparable. Equipment AIS or GIS must be selected based on the equipments ratings and capabilities to satisfy actual application requirements. GIS technology integrates common database operations such as query and statistical analysis with maps.

Who would have thought that a human can clone a species. The LCC comparison of AIS and GIS is as follows. A major difference between conventional air insulated substations AIS and the gas insulated substations GIS is that the SF6 gas insulated electrical components are placed within an earthed pressurized metallic container.

However GIS requires minimal or no maintenance over long periods compared to regular or more. What is the difference between the distribution stations. According to Prof.

Enclosures are of aluminium alloy or stainless steel. Land Information System is used for land record and cadastral in the accurate reliable and current format for an associated attribute. However for the many substations projects around the world GIS offers the obvious choice.

The purpose of the following report is to provide a cost and technical comparison between Air Insulated Switchgear AIS and Gas Insulated Switchgear GIS substations for the purposes of building a 400kV Substation for the Laois-Kilkenny Reinforcement Project. Wherever land is a constraint GIS is the only option. Sulphur Hexafluoride SF6 gas the primary insulating medium.

Understanding differences between GIS and AIS in five points. What is the difference between AIS and GIS SUBSTATION. Database Management Systems and GIS Design Overview This presentation deals with the relationship between database processing requirements database management systems and GIS database design theory.

Question added by مصعب احمد عباس احمد electrical engineer Electricity. SF6 gas- superior dielectric. Enclosed in a ground metallic housing.

However such a com-1 parison does not take into account the fact that by locating a GIS transformer substation close to the load centers a far. A direct comparison of the component investment for identical switchgear con-figurations suggests that the GIS variant is more costly than the air-insulated switch-gear AIS solution. Difference Between AIS and GIS AIS vs GIS Undoubtedly our technology has advanced even to the most unimaginable things.

Many considerations must be taken into account before selecting the electrical medium-voltage MV switchgear that best meets a users needs. In this GIS or gas insulated switchgear system than one functional element are encapsulate in a single metal enclosure. INDIA Population Nearly 20 of worlds population Area Nearly 24 Adult literacy Less than 50 2060 18 billion population 400 M tonnefood.

For example in some design a three phase circuit breaker current transformer earth switches even other feeder elements are covered together in a single metal capsule. Adjacent modules are joined by means of multi-bolts tightened on flange. Hybrid Technology that is a mix of AIS GIS combines the benefits of both AIS and GIS Initial capital cost -20 higher than AIS.

Primary hardware for primary equipment GIS is more expensive than AIS. This is due to the technological and economic advantages associated with GIS over AISWell the only downside is the global warming issues associated with CFCs. Goodchild at the University of California at Santa Barbara geographic information science or GIScience is the study of the theory and concepts that lie behind GIS and the other geographic information technologies and considers fundamental questions raised by the use of these systems and technologies.

A very short clip presenting the simple basic differences between GIS AIS Sub-Stations. This is a significant change in operating the switchgear with circuit breakers disconnectors and switches earth. A geographic information system GIS is a computer-based tool for mapping and analyzing features and events on earth.

Substation Automation Electric Power Electrical. Until the time SF6 is banned it remains the best option. Gas filled modules have nonmagnetic enclosures.

Cost Comparison between AIS and GIS in terms of Cost Air Insulated Gas Insulated Factors for Life Cycle Cost Substation Substation Planning and Engineering 100 80 Real Estate land requirement 100 25 Primary Equipment 100 150 Secondary Equipment 100 100 Earthwork Civil work structures 100 60 Electrical assembly and erection 100 70. Who would have thought that a human can control things with just a press of a button. Double 400kV Busbar and Double 110kV Busbar Technically both AIS and GIS.

However the price of auxiliary equipment such as support conductors land installation control protection and monitoring can lead to a cost difference between the two systems being small. BY GAETAN DJENANE Schneider Electric Inc. From a management perspective considerations include the purchase price the life expectancy of.

Who would have thought that a human would be able to fly. Data Data Models and Databases Data has been defined as a collection of facts concepts or instructions in a formalized. But because it contains a larger amount of SF6 gas losses are higher in GIS substation than in AIS one 11 The AIS Live Tank substation requires a larger amount of electric energy than the GIS.

Introduction to GIScontinuedThe atmospheric air insulation used in a conventional AIS requires meters of air insulation to do what SF6 can do in centimeters. The following was compared for both AIS and GIS.
