Is Humidity Causing an Error?

Posted by Sarah Landeen on May 31, 2017 3:55:50 PM

Has your cable ever failed and the tester reports and IR or HV leakage error? Maybe you found the cause of this error, but maybe you are still speculating.

Try testing again. It fails again.dampcable.jpg

You test the cable several more times and eventually it passes. You haven’t changed anything, but the cable passed the test.

Why is that? A likely answer is because you were testing in high humidity.

You don’t need to spill your protein shake on the harness board for moisture to make the cable to fail. Insulation can absorb moisture from humidity in the air, increasing the probability of an insulation resistance failure.

If you think humidity might be responsible for causing your cables to fail, Cirris has some solutions. Check out the article in our Learning Center.
