Hi Scott,
In your last posting, you said:
Also had another failure problem. This time, one system and three testers.
Two testers failed the system while one passed it. This problem was with
ramp rate. That is, how long it takes to go from zero volts to 1,500 VAC.
Again, there is no specified ramp rate in the standards and is set at
manufacturer's choice. All three testers had different ramp rates (375
V/sec to 200 V/sec). Slower rate passes while faster rates failed. Finally
set all three to 100 V/sec and problem solved.
So...., if slower rate passes, why was the ramp time set much, much faster?
Just a little curious.
Best regards,
