- 4T- Limiting Arc Flash Exposure$60.00Learn More
Arc flash incidents may happen despite care taken to avert them. In such circumstances, it is always better if the incident energy is low and staff is ready for the worst by implementing adequate PPE. Arc flash incidents can be cut down by use of adequate equipment, proper preventive care, planning and coordination of operation, as well as skill improvement and real experience. Also crucial is the mental and physical circumstances of the staff such that the dropping of equipment and tools, accidental touching, etc., are averted.
This course is suitable for engineers with a desire to understand the how to limit arc flash exposure. Course covers discussion on preventive operation, limiting fault currents and adjustments of protection settings and personal protective equipment.
Learning Objectives
This continuing education course is intended to provide you with the following specific knowledge and skills:
Limiting arc flash exposure
System preventive operation
Limiting short circuit currents and arcing times
Adjustment of protective settings
Personal protective equipment selection

Recent Trends and Innovations in Arc Flash Assessment
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.

Arc Flash Hazard Calculations in DC Systems
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.
