- The calculated incident energy is reduced by FU-UTIL-1 at SE-1 from 16
- cal/cm2 to 1.9 cal/cm2.
¢ºSecond Case (With Protection) Primary Protection: Relay Secondary Side Voltage: 4.16 kV The calculated incident energy is not reduced by REL-UTIL-2 at SE-2. It remained at 21 cal/cm2. Lowering the time delay settings (but sacrificing downstream coordination) could achieve more mitigation. ¢ºThird Case (With Protection) Primary Protection: Fuse Secondary Side Voltage: 480 V The calculated incident energy is not reduced by FU-UTIL-3 at SE-3. The clearing time of the fuse is above the maximum arcing time of 2 seconds. ¢ºFourth Case (With Protection) Primary Protection: Relay Secondary Side Voltage: 480 V The calculated incident energy is reduced by REL-UTIL-4 at SE-4 from 154 cal/cm2 to 24 cal/cm2. ¢ºSummary Case 1°ú Case 4¿¡¼ 1Â÷ º¸È£(primary protection)´Â »ç°í ¿¡³ÊÁö ¿ÏÈ¿¡ Å« ¿µÇâÀ» ¹ÌÃƽÀ´Ï´Ù.
