13/06/2017SafeRing AirPlus was launched last year and is the first 24 kV medium-voltage RMU with an alternative to SF6 on the market. The RMU makes use of AirPlus, a new fluoroketone-based gas mixture developed by ABB in collaboration with 3M. The new gas has a global warming potential (GWP) of less than one - almost 100 percent lower than SF6.[email protected]

May 20, 2020SF6 gas plays a key role in switchgears and the percentage of gas purity has a direct effect on the switching. Commercially, SF6 is supplied in pressurized bottles or liquid tanks. The gas of these bottles has a minimum degree of purity of 99.9% and may possess the following impurities according to IEC 60376: carbon tetrafluoride (CF4) <0.03%
The SF6 LASERCHECK P3:atm uses a novel principle of leak testing (patent pending). The windowed detection chamber inside the system is illuminated by a specifically developed CO2 laser. A sample of the gas mixture from the test chamber is transferred to the detection chamber via a measuring probe. If the sample contains SF6 released from the
15/04/2015TechTopics No. 111. SF6 gas and U.S. greenhouse gas emissions. The use of sulfur-hexafluoride (SF 6) gas globally has been the subject of a large amount of discussion for many years, both in the U.S., and worldwide. SF 6 is recognized as an extremely potent greenhouse gas, primarily because of its atmospheric lifetime of about 3,200 years, with
Recent European and North American legislation has focused on greenhouse gases such as SF6, with the target of reducing emissions to 0.5% per annum. As a result, gas density monitoring is essential to improve leakage visibility, notwithstanding the superior performance of modern gas isolated switchgear (GIS).

IEC 60480 : Specifications for the re-use of sulphur. IEC 60480, 3rd Edition, April 2019 - Specifications for the re-use of sulphur hexafluoride (SF6) and its mixtures in electrical equipment This document provides criteria for the re-use of sulphur hexafluoride (SF 6) and its mixtures after recovery and reclaiming from electrical equipment (e.g. for maintenance, at the end-of-life).
This TB reviews insulation co-ordination related to internal insulation of gas insulated switchgear (GIS) in SF6, and also some aspects of N2/SF6 gas mixtures under AC condition, considering the current worldwide issues and referring to the latest research on the insulation properties and techniques.
In all these applications, gas-insulated switchgear technology from Siemens provides exceptional advantages in respect of climatic independence, personal safety and maintenance-free design. For the customer, this offers the high benefit of maximum supply reliability in his network, both as a provider of customers and as an energy supplier for production processes.
05/02/2021Gas Insulated Substation has gas monitoring system. Gas inside each compartment should have a pressure of about 3kg/cm 2 .The gas density in each compartment is monitored. If the pressure drops slightly, the gas is automatically trapped up. With further gas leakage, the low pressure alarm is sounded or automatic tripping or lock-out occurs.

Advantages of sulfur hexafluoride vacuum in United States14/10/2020It is used as an isolation gas because, in these high voltage ranges, the surrounding normal air would not serve as insulation. However, sulfur hexafluoride is very damaging to the environment, so it is important that this gas does not permeate the Earth's atmosphere.
