Case studies
Arc Flash & Power System Study Case Studies
Real engineering results from real facilities — how standard updates and modeling choices change the numbers behind your PPE requirements, labels, and equipment ratings.
Arc flash · IEEE 1584
A hospital switchboard: 34.56 cal/cm² under the old standard, 23.56 under the new one
We recalculated a county hospital's 480Y/277V system under both IEEE 1584-2002 and IEEE 1584-2018 — same gear, two editions of the standard, and materially different PPE requirements and labels.
Short circuit · VFD modeling
700+ buses, 88 VFDs, one panel where bypass mode changed the answer
On a 700+ bus SKM model with 88 bypass-capable VFD motors, we compared short circuit currents in bypass versus normal mode — and whether one panel exceeded its rating turned entirely on that modeling choice.
