This step is used to adjust the incident energy from the normalized 24 inch 610 mm working distance to the actual working distance d used for the equipment under study.

An incident energy.

Incident energy worksheet b is used to convert the normalized value to an incident energy at a specific working distance and arcing time used in the study. In most cases the incident energy depends on three elements. An understanding of the potential incident energy that could be generated by a system is important for knowing the amount of protection needed against arc faults. The unit of incident energy is cal cm 2.

Incident energy is the amount of thermal energy projected onto a surface at a distance from the source produced during an electric arc event. While incident energy is everywhere it is most commonly associated with a few specific things. A contractor has downplayed an incident which took place during work to dismantle what s left of the buchan alpha oil rig after footage appeared online. Figure 3 shows the incident energy analysis process.

Incident energy is a measurement of energy usually heat striking a surface. This is a major part of the design and refinement of. Incident energy analysis process. The most common form of this energy is thermal energy from heat sources.

Solar sciences refer to the amount of incident energy absorbed by objects meaning the amount of solar energy they take in. One cal cm 2 is equivalent to the amount of energy produced by a cigarette lighter in one second. It is the incident energy that causes burns to the human skin. The most common distance for which incident energy has been determined in tests is 18 inches.

If you were sitting near a campfire the warmth you would feel would come from the radiant heat of the fire and it could be measured in terms of incident energy. The standard ieee 1584 ieee guide for performing arc flash hazard calculations provides the equations used for the calculations usually performed with arc flash software. The anti arc dimension is the value assigned to a material to describe its resistance to arcing. Incident energy the severity of an arc flash is defined by the prospective incident energy and is normally determined by performing an arc flash study.

These are the steps to include in an incident energy analysis process. In the united states an analysis of the potential incident energy that a worker could be exposed to in the case of an arc fault is a requirement under osha standards 1910 and 1926. The unit of incident energy is cal cm 2 the threshold value of incident energy for 2 nd degree burn of the human skin is about 1 2 cal cm2. The working distance is the distance from where the worker stands to the flash location.
