LS Electric Power Testing Technology Institute (PT&T), regarded as the top private power testing laboratory in Korea, announced on the 26th that it has doubled the capacity of its short-circuit generator, advancing to become the 6th largest testing facility in the world.

On the same day, LS Electric held a completion ceremony for the second PT&T short-circuit generator at its Cheongju 2nd plant. About 100 people attended the ceremony, including CEO Koo Dong-hwi, Jin Jong-wook, Director of the National Institute of Technology and Standards, Kim Nam-gyun, President of the Korea Electrotechnology Research Institute, Park Ji-hyun, President of the Korea Electrical Safety Corporation, and Lee Joong-ho, Director of the KEPCO Power Research Institute.

A short-circuit generator is equipment used to verify and evaluate the performance of power devices such as circuit breakers and transformers. It simulates fault currents that can be tens of times higher than normal currents in actual power systems.

Since 2020, LS Electric has invested 30 billion KRW to expand the short-circuit generator capacity due to a surge in product testing demand.

PT&T added one 2000 MVA (Mega Volt Ampere) class generator, enabling independent and parallel operation of two generators. This is expected to resolve testing delays that previously took an average of two months and increase testing efficiency by over 85%.

The number of testable devices increased from 25 to 41 after the expansion. It is anticipated to strengthen the capability to handle UL certification tests, which is necessary to meet the rapidly growing demand for power devices in North America.

PT&T had been recognized as a top 10 global testing facility with one 2000 MVA short-circuit generator. With this expansion securing a total capacity of 4000 MVA, it rose to 6th place globally. It now stands alongside ABB, following Italy's CESI (KEMA), Korea Electrotechnology Research Institute, Siemens, and Toshiba.

An LS Electric official stated, "This expansion demonstrates a strong commitment to becoming a market-leading company through bold investment amid increasing global uncertainties."
