Arc Flash Hazard Calculations in DC Systems

The Arc Flash Hazard Calculations in DC Systems 3 hour PDH online course is a part of the Electrical category courses.

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 course is suitable for electrical engineers with a desire to understand DC system fault calculation followed by DC system arc flash calculation. Presented details cover issues related to DC fault calculation, DC protection equipment and DC arc flash energy 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.

Learning Objectives

At the end of the course you will gain the following knowledge and skills:

  • DC system fault calculation methodology
  • Short circuit current calculation of DC elements such as batteries and rectifiers
  • DC circuit breakers and fuses
  • Calculation of incident energy in DC systems
  • Protection of semiconductor devices
