Arc Flash Hazard Calculations in DC Systems

COURSE NO: E03-035
PDH CREDIT: 3
Arc Flash Hazard Calculations in DC Systems
Course Highlights

This online engineering PDH course presents details cover issues related to DC fault calculation, DC protection equipment and DC arc flash energy calculation.

 

IEEE 1584 standard does not discuss arc flash hazard calculations in the DC systems. Standard NFPA-70E- 2000 provides a short calculation method. Therefore, the current literature is lacking calculations of arc flash hazard in DC systems. The necessary calculation steps are very similar to calculations in AC systems, however there are marked differences, particularly with respect to protection, cause of short-circuit currents in the DC electrical systems, and the current interruption devices in DC systems, which function fast to limit the energy let-through.

 

This 3 PDH online course is suitable for electrical engineers with a desire to understand DC system fault calculation followed by DC system arc flash calculation. Upon successful completion engineers will be able to address DC system fault calculation methodologies, basics of the DC protection equipment and methods to calculate incident energy in DC systems.
