1 second. 157. These values are adopted in IEEE Guide 80 [21]. 6). Other researchers have suggested different values of IB. In 1936, Fwerris et al. [26] suggested 100 mA as fibrillation threshold; this value was derived by extensive experimentation at Columbia University. Some more recent experiments suggest the existence of two thresholds: one for shock duration less than one heartbeat period, and the other for the current duration longer than one heartbeat period. For a 50 kg body weight, Biegelmeier [27] proposed threshold levels of 500 and 50 mA, respectively.

Proper mitigation of harmonics from nonlinear loads should be provided. 9. In industrial environment all electrical equipment should be heavy duty to endure more frequent usage and for reliability. The listed equipment should be provided, 10. A reliability analysis of the distribution system in the design stage should be conducted. This list of tasks for effective planning and development and for meeting the specific performance requirements of electrical power systems can be long—depending upon the electrical power system under consideration.

Thus, not only an accurate calculation of incident energy level, but its reduction in the planning and design stage and selection of appropriate protection and relaying of electrical systems are gaining importance [36]. A very significant change in NFPA70E 2012 from 2009 is the redefinition of PPE hazard risk categories. This will be based on developing a clothing system meeting a specific tested cal/cm2 level and comprised of arc-rated materials. Suppose that an 8 cal/ cm2 protection is required; this can be achieved by: • 8-cal/cm2 arc-rated pants and shirts • 4-cal/cm2 treated pants and shirts and 4 cal/cm2 arc-rated overall • 8-cal/cm2 arc-rated overall cotton shirts and pants.
