K6 gas is ecologically friendly with a global warming capacity of less than 1, and does not consist of any serious harmful components. The boiling point, which is a prerequisite for applying gas to power gadgets, is also low (– 26 ° C), making the gas applicable in most areas.

Effect and Future Plans.
KERI went even more to use K6 gas to ultra-high voltage (145kV) transmission-level breaker and even passed the Interrupting efficiency test in accordance with the international requirements of the International Electrotechnical Commission (IEC). In particular, ultra-high voltage transmission circuit breakers are thought about to be the most difficult areas to apply insulating gas.
Based on the results of the test, KERI plans to use K6 gas to various power devices (breakers, transformers, switches, and so on) from circulation to transmission.
Dr. Yeon-ho Oh, head of Eco-Friendly Power Apparatus Research Center, KERI stated, “K6 gas has better efficiency and is more eco-friendly than other insulating gas that has been led by sophisticated abroad companies.” He included, “As Korea has the top-tier position in export in the worldwide power device market, the development of K6 gas will have a huge impact not only on the environment however likewise on the commercial and economic front.”.
Based on the accomplishment, it is planned to prepare for commercialization with innovation transfer to Korean power device business. KERI is dedicated to contributing to strengthening the competitiveness of the domestic power device market by developing clear style standards for the large use of environment-friendly gas through constant interaction with the market.
KERI is a government-funded research study institute under the National Research Council of Science & & Technology of the Ministry of Science and ICT. This study was conducted in partnership with the Korea Research Institute of Chemical Technology, Korea Research Institute of Standards, Korea Institute of Fusion Energy, and Korea Institute of Toxicology.
Difficulties in developing an alternative gas for SF6: Different guidelines on using chemicals in each nation, and as it is a delicate chemical compound, litigations might emerge due to different interests of nations, it is challenging to be developed by private companies in a short duration of time (expense and time needed, high possibility of failure), absence of capability to evaluate gas products, etc.
In spite of this high possibility of failure, KERI embarked on the research and advancement with the mission of a national research institute to react to global carbon emissions guidelines and the huge effects expected with the effective development of SF6 alternative gas.

Among the gases presently utilized in market, compounds with a low global warming potential were sorted out, and the chemical and electrical homes of the picked primary prospects were carefully examined to figure out the 2nd round prospects.
Advancement of K6 Gas
The last prospect products were selected based on the outcomes of insulation and explosion/ignition control performance tests, and the optimal ratio for application to power devices was derived to develop environmentally friendly insulating gas. KERI called this separately developed gas K6..
In Korea, as SF6 gas represent 60% of the overall greenhouse gas emissions released by KEPCO, research on the advancement of alternatives is urgently required to react to the climate crisis and accomplish carbon neutrality.
Challenges in Developing Alternatives
Although much effort is being made worldwide to establish an environmentally friendly gas that can replace SF6, it has yet to bring impressive results, as establishing a replacement gas for SF6 is more difficult and challenging than establishing new drugs.
The Korea Electrotechnology Research Institute (KERI) has actually developed K6, an eco-friendly insulating gas, as a sustainable option to sulfur hexafluoride (SF6), which is detrimental to the environment. K6, with its low worldwide warming potential and non-toxic nature, has been effectively applied to ultra-high voltage breaker and is expected to revolutionize the power devices field, minimizing greenhouse gas emissions and contributing to environment modification mitigation.

The Korea Electrotechnology Research Institute (KERI) has actually developed a pioneering eco-friendly insulating gas to replace sulfur hexafluoride (SF6), a substantial factor to worldwide warming in electric power equipment, and developed a style innovation to make it applicable to ultra-high voltage transmission circuit breakers.
Obviously, power gadgets need to have the ability to perform electrical power well however an insulation function to block electrical power is likewise vital to prepare for unexpected accidents and for safety reasons. SF6 gas uses outstanding insulation and with far superior arc extinguishing efficiency than any other gas, which interrupts fault current in case of a system failure, it has been utilized in the power devices field for over 50 years.
The Problem with SF6
The global warming capacity of SF6 is 23,500 times that of carbon dioxide, and as soon as leaked into the environment, it remains for as long as 3,200 years and has a negative impact on the environment.
K6: suggesting K of KERI + last compounds were obtained in the 6th times in the 2nd round prospect group.
