He also earned a master's degree engineering from the same university and an MBA degree from the Hong Kong University of Science and Technology. Cheng has completed arc flash calculations (ac and dc) for major utilities and corporations across North America and was involved in the arc flash testing for OPG, IEEE and EPRI.

Kinectrics has almost a decade of experience in applying these techniques and, during that time, the company has tested more than 1,715 km of cable operating at 66 kV and up. The tests have covered 307 individual phases, 614 terminations and 2,654 joints and it is in interesting to note that failure rates have remained substantially constant ...

Arc Flash study. The Electrical Consultant/Contractor shall perform a study for the purposes of estimating worst case available short circuit current values and Arc Flash incident energy. The final study will be generated based on the final electrical equipment submittals and the final pulled conductor lengths for all feeders.

Kinectrics has done testing on single phase arcs and is in fact the basis for NESC arc flash tables. I believe work was originally done by Ontario Hydro. It appears that OSHA will be recognizing this work as an accetable method in the future. The range of testing does include low voltage. I do not see anyone referencing this work or software.

What Are the Types of Incident Energies?In an arc flash hazard analysis there are two distinct values of incident energies to be considered depending on the type of equipment and if the equipment has a main breaker. Switchgear, switchboards, and panelboards (to name a few) with main breakers will have line-side incident energy values and load-side incident energy values.
