Low Voltage 170 VAC Arc Calculation
Low Voltage 170 VAC Arc Calculation
(OP)
The IEEE 1584 caclulations are for 200 VAC and up for small arc gaps.
Has anybody seen information on whether or not an arc between a three phase 170 VAC supply will sustain on high current systems for gaps ranging from 3 inches to 12 inches? The available fault current is approx 200 kA.
I am also looking for information on arc energy between one phase of the AC supply above and the 90 VDC bus within the rectifier.

RE: Low Voltage 170 VAC Arc Calculation
There is a lot of additional testing being conducted. You might try contacting someone on the IEEE 1584 committee.
As for the ac to dc scenario - I have no idea. Is there really a current path?
