New equipment and innovations are marking improvements in arc flash systems and give a safer work environment for the staff involved in maintenance of the electrical equipment. Also some old established methods are being revisited. Coordination of instantaneous devices in series is a new field, as well as the development of current limiting low voltage molded case circuit breakers. There are also innovations in the construction of low – voltage MCCs, new breed of low - voltage trip programmers, remote racking of MCC buckets etc. This course is appropriate for electrical engineers with a desire to learn about the recent trends and innovations in the arc flash assessment. Upon successful completion engineers will be able to address low and medium voltage protection principles, arc flash hazard reduction techniques and new equipment design features that are used for arc flash reduction.
