 ¢ºFirst Case (With Protection)

Primary Protection: Fuse. 

  • Secondary Side Voltage: 4.16 kV
  • 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.
