Greetings
Since founded in 2001, we, Power TOS, have provided the services of reviewing the technologies of power systems, testing/commissioning/diagnosing protective relays that are installed in nuclear/hydro/thermal power plants, and consulting power systems, keeping in mind our mottoes of "settling the culture of testing power systems", "dream and intention", and "customer impression".

Through the improvement in power quality, we intend to make a contribution to the society.  In addition, we participate in the projects of designing and manufacturing protective distributing panels and in the projects of developing and applying high-tech digital facilities that are essential for power systems.

On the other hand, we purport to lead the future of the power industry by making an advance into the projects of diagnosing the power systems in the world, such as Middle East, Asia, and Africa. Having dreams and wills, we will strive to construct human infrastructure and to create blue ocean to stand up in the center of the power industry and the world. Under the paradigm of boundary-free unlimited competition, changes and innovation of pursuing global standards are the absolute conditions for a company????????urvival.

Coping with this, we will increase your values and impress you through the best quality and perfect services, through which we will become the most reliable business partner. We would like you to give us your continuous interest and love, and we wish your prosperous development. Thank you very much.  

YEW, KEUN-SOO, CEO
