METER OR DISPLAY DEVICE FOR CALCULATION AND DISPLAY OF ARC FLASH INCIDENT ENERGY

摘要

A meter or display device (4;14;130;142) for at least one power circuit zone (42;54;56;58). The device includes a processor (144) having a plurality of dynamic inputs (146), a routine (62;64;66;68) and an output (148). The routine is structured to input the dynamic inputs, calculate (76) incident energy of one power circuit zone of the at least one power circuit zone, and output (77) the output. A display (6) is structured to display at least the calculated incident energy (8) from the output of the processor.
