| Abstract |
Capacitor switching is essential for the economic operation, and proper voltage control of KOREA electric utility distribution system Voltage transients produced by capacitor switching (around 2.0 per unit at substation and 2.5 or less per unit at customer site, and lasting less then I[㎳]) do not have the magnitude or duration to interfere with the operation of computers, but they do disrupt the operation of adjustable speed drivers, The result of our research, ASD manufacturers should learn from the computer industry and design products that will operate satisfactory in the electrical envelopment in which they will be placed. In this case history, the inductors on the input to ADSs in order to prevent nuisance tripping from capacitor switching(and other causes within the apartment) proved to be an effective, low-cost solution. |
