I am trying to recognize/detect a parallel arc in a low voltage 25 Volt DC application. The arc's are anticipated to occur when a small motor (2 amps) and/or a larger motor (20-90 amps) are being used. It is possible that the arcs may occur when the motors are idle also. The use of these motors is frequent but not constant throughout the day and will stay on for a few seconds to a few minutes and on rare occasions, a few hours. Obviously, the arc's are going to be disguised by the inevitable electrical noise generated by the motors. Setting the parameters of the RD-195 could be a bit tricky.
Has anyone been successful in determine an arc in this condition?
