Arc FLash ArcPro vs PSCAD

[ShawnSafxxx]

Does any one have a user manual for ArcPro? If so I need a copy.

Is there a software that could be used for realistic results for voltages above 15kv, since 1584 with the Lee equations are out to lunch for those voltages. Is PSCAD any good? I'm in seach of a software where the complete system can be modeled as oppose to just one location at a time.

The SKM Power Tools software has an Arc Flash module. Might be worth a look at.

You can probably get a copy of the ArcPro manual for evaluation from Kinectrics. Contact info is at

SKM and Cyme have an NESC arc flash option that uses the NESC-2007 tables. This ends up being much more conservative that using ArcPro because there is no interpolation. The NESC tables do not show fault currents below 5 kA, so for a fault at a distance from the substation where the current is down to 2 kA with a slower trip time, you get a high value of incident energy because you have to use the 5 kA value. I have found using ArcPro that the worst case incident energy is generally at the substation where the fault current is higher even though the clearing time is lower.

I just today received an EasyPower upgrade that adds the NESC open air calcs as an optional arc-flash calculation method. So that looks like another possibility to consider.

We currently use the SKM PowerTools for all of our Arc Flash and power study requirements and, despite the many bugs it has, works well for what we use.

Not to hijack the thread but how does PSCAD go with Arc flash? Can you model complete systems or is it more of a real time style application for circuits?
