Our knowledge and technology have finally caught up with the level of the manufacturers and we are finally able to take the lead on planning.

Failure is not an option when conducting equipment retrofitting work. This was a project involving high levels of responsibility, as any errors in the design or construction might affect the entire southern power generation facility. The most important work, which accounts for the majority of the modifications, was the enhancement of the "protective coordination equipment" that disconnects the accident point within the shortest possible time in the event of an electrical accident and continues to supply power to normal circuits. I worked with the manufacturer on the design of this equipment, but in the first few months I lacked the necessary skill in reading the drawings and was unable to understand the manufacturer's proposal.
Nevertheless, as I read through the huge volume of more than 200 drawings, I gradually began to grasp the whole picture. I even reached the level where I was able to make proposals as well. As design and construction proceeded, we completed a series of unit tests with favorable results, and it was truly like a weight had been lifted from our shoulders. At the same time, I felt that I had acquired valuable experience and that my technical skills had improved significantly.
