Furthermore it is shown how costs can be reduced by the application of different maintenance strategies. They are in extensive use in areas where space weather conditions seismic occurrences and environmental concerns are not an issue such as rural areas and favourable offsite.

Maintenence and access roads.
Gis and ais. For this network the impact of the application of air insulated substations AIS and GIS-Substations on the whole system costs is compared. Actually most substations across all regions are AIS. Transformer oil pit.
In the US the Coast Guard and commercial vendors collect AIS data which can also be used for a variety of coastal. Furthermore GIS substations take up less space compared to AIS. GISAIS cost comparison and compare the respective cost of the AIS and the GIS variant the figures for the different components and external ser-vices apply to the German market.
Thats because they present front rather than rear access. Through the use of common routines and methodology future AIS processing and analysis can be conducted by UK administrations to a consistent and commonly agreed approach. The results depict the main cost-drivers as well as the most important elements of the system.
A concept and definition. Recently we had to change a GIS design to AIS due to an instruction from one of our clients. Various arguments exist around SF6 Gas Insulated GIS and Air Insulated AIS switchgear.
Flexibility in term of future expansion in Hybrid technology is high similar to AIS. And international waters in real time. Both AIS and GIS are advanced technologies to track your activities.
However GIS requires minimal or no maintenance over long periods compared to regular or more frequent maintenance for metal-clad hence in the long run GIS may offer. Gas Insulated or Air Insulated Switchgear. As a result GIS is more reliable requires less maintenance and will have a longer service life more than 50 years than AIS.
A load growth of 15 per year linear was set and the cash value calculated for a planning horizon of 10 years. They also include its incorporated testing instruments. Arc flashes are occasional in GIS.
Modular to suit virtually any network concept. Thats because all other interior essentials are insulated. GIS use approximately 80 of all SF6 produced.
Hybrid Technology that is a mix of AIS GIS combines the benefits of both AIS and GIS Initial capital cost -20 higher than AIS Hybrid technology requires moderate land size 50 of AIS and 50 higher than GIS. Portable power solutions increase grid development agility and resilience. Sinchrony plan bundled civil and electrical layout.
11 Scope of Work The scope of work of the Laois-Kilkenny Reinforcement Project is to develop a new 400110 kV substation and associated 110kV circuit in order to reinforce the general areas of Kilkenny Laois Carlow and Kildare by way of improving quality. Outstandingly compact thanks to the hybridization of GIS and AIS technology. Coast Guard through an onboard navigation safety device that transmits and monitors the location and characteristics of large vessels in US.
It consists of following items. Clearly structured with good access to all equipment. Dead tank compact DTC circuit breakers.
GIS is Gas insulated substation. By Steven McFadyen on August 11th 2009. A GIS is mostly used where space is expensive or not available.
In this all switchgears and other devices are enclosed inside gasfilled metallic chambers. While an AIS is normally filled with air and hence does not have a significant climate impact majority of the GIS are based on SF6 the most potent greenhouse gas that is 23500 times stronger than CO2 in terms of its global warming potential. The AIS uses air as the primary dielectric from phase to phase and phase to ground insulation.
Equipment AIS or GIS must be selected based on the equipments ratings and capabilities to satisfy actual application requirements. B design and development. Latest posts by Celine.
His concern is the global warming potential of SF6. Vessel traffic data or Automatic Identification System AIS data are collected by the US. Wherever land is a constraint GIS technology should be adopted.
GIS is massively simpler to handle on a daily basis. There is no difference in efficiency. In a GIS the active parts are protected from deterioration from exposure to atmospheric air moisture contamination etc.
Portable power solutions Flexible robust plug and play. Technically both AIS and GIS substation types are considered acceptable for the requirements of the Laois-Kilkenny Reinforcement Project. AIS means Automatic Identification System while GIS means Geographic Information System.
An in-terest rate of 8 and an inflation of 3 were assumed for the calculation of the cash values. Medium Voltage Distribution Catalogue I 2012 Air Insulated Switchgear up to 24 kV MCset SF6 withdrawable circuit breaker PIX vacuum withdrawable circuit breaker Make. They are compact and occupies very small area.
Keywords Life Cycle Assessment Global Warming Potential Life Cycle Cost Circuit Breaker Power Supply. In addition to the. AIS is conventional Air Insulated substation.
The optimisation of GIS technology with respect to lowest life cycle cost highest availability and zero-maintenance has made GIS competitive with AIS not only at special application fields. This project has developed flexible data processing tools and associated geographic information system GIS procedures to decode and display AIS data. A very short clip presenting the simple basic differences between GIS AIS Sub-Stations.
A long with eletrical design for high voltage GIS and AIS substaton we create civil work design in this field as well. They have been in use for years before the introduction of GIS. AIS is used for towing and navigating ships while GIS is used in many fields like housing and real estate crime prevention traffic improvement etc.
As a result GIS and AIS technology achieve similar ranking values depending on the specific assessment. The cable compartment is the only one accessible. Foundation design and calculations for gantries lattice towers supports for electrical equpiment.
GIS equipment offers a smaller footprint and space savings but may have higher initial cost.
