NEWS 48-Year KEPCO Partner, Poongsan Electric Featured by Korea Electric Times for Transformer Testing Excellence

DATE2026-07-07

 

Poongsan Electric, a transformer manufacturer with a 48-year partnership with KEPCO, was recently featured by Korea Electric Times, one of South Korea's leading publications covering the electric power industry. The article highlighted the company's comprehensive transformer testing process and its commitment to delivering reliable, high-quality products for the power distribution network.

 

Before being installed in KEPCO's power distribution network, transformers supplied to the utility must successfully pass rigorous inspections conducted in cooperation with KEPCO's Power Equipment Testing Center. These evaluations verify that each unit meets strict utility standards for electrical performance, operational safety, and product reliability.

 

The feature provided an inside look at several critical testing procedures conducted in cooperation with KEPCO inspectors. Among the most important are the Induced Voltage Withstand Test, which verifies insulation integrity by applying voltages significantly higher than normal operating conditions, and the Temperature Rise Test, which confirms that the transformer can operate continuously under load without excessive heating. Together, these tests ensure reliable performance throughout the product's service life.

 

 

The article also emphasized Poongsan Electric's approach to quality management. Beyond complying with KEPCO's inspection requirements, the company applies additional internal quality control standards throughout the manufacturing process to further enhance product consistency and minimize the possibility of field failures after installation. For nearly five decades, Poongsan Electric has built its reputation on rigorous testing, strict quality control, and dependable manufacturing.
