The Korea Electrotechnology Research Institute (KERI) successfully held the 37th IEC TC95 international conference for the first time in Korea to discuss the standardization and revision of 'protection relays', a key device in power systems.

The IEC (International Electrotechnical Commission) is a non-profit organization that promotes international standardization of electrical and electronic technology, and TC95 is responsible for establishing and revising standards in the field of protective relays.

This meeting was held at the Rise Autograph Collection Hotel in Seoul from May 20 to 23, and was attended by experts from global manufacturers such as Siemens, ABB, and GE, as well as testing and certification agencies such as Europe's DNV-GL and China's State Grid, and power system operators.

A protective relay is a device that detects and quickly recovers abnormal situations such as overcurrent and short circuit, and plays a key role in protecting equipment and people and maintaining the stability of power supply. Accordingly, the IEC TC95 meeting has been held continuously since the first meeting in 1995, and this time it was held for the first time in Korea, rather than in advanced countries such as the United States or Europe.

At this meeting, various standard establishment/revision agenda items were discussed, including △Electromagnetic Compatibility (MT2) of protection relays, △Safety Standards (MT3), and △Directional Overcurrent Protection Relay Elements (MT4).

KERI Electric Energy Evaluation Center Director Sangpil Ahn said, “Hosting the IEC TC95 meeting in Korea provided an opportunity to elevate the research institute’s status and strengthen its testing and certification technology,” and “We will strive to more actively reflect the opinions of domestic companies in the international standardization process, which will greatly contribute to the development of the national electric power industry.”

KERI is a government-funded research institute under the National Research Council of Science and Technology of the Ministry of Science and ICT. It serves as an internationally accredited testing and certification agency for electric power equipment and supports domestic companies in improving their technological capabilities and developing overseas markets.
