Arc Flash Calculations:
Arc flash calculations show that PPE clothing can be worn to increase personnel protection for all the locations. Arc flash warning labels provided for these locations indicate the PPE required to be worn. The engineer recommends that the arc flash warning labels be installed on the electrical equipment to warn personnel of the potential hazard.





SKM PTW Arc Flash calculates the incident energy and arc flash boundary for every location in a power grid. Arc flash saves time by mechanically determining trip times from protective device settings and arcing fault current values. Incident energy and arc flash boundaries are calculated following the NFPA 70E, IEEE 1584 and NESC standards.
