<Before : Separate Type Program >

* Field Analysis (Commercial) + Evaluation (Hyosung)

<After : Combined Type Program (EST – Dielectric analysis)>

* Field Analysis(Hyosung) + Evaluation(Hyosung)

- The Dielectric analysis program has been developed and applied , which can allow not only easy approach for designers, but also reduction of lead-time for the designing process by conducting analysis and evaluation process at the same time. This program can be applied to every type of Hyosung’s TR up to 800kV Class.
