HV Test in Isolators
Hi Everyone.
I am quite curious with digital isolators. I have read that these parts are being tested at a high voltage (kV) to ensure the durability and quality of devices over a life time. The HV testing includes Partial Discharge test and Leakage Test. If the supporting bodies such as UL, VDE and CSA are ignored/not be used as a point of "NOT POSSIBLE", is there a way that the breakdown of ions or forcing stresses in an isolators be possible? i.e. testing it in a lower voltage but longer period of time. Use a DC voltage? Or a way that it could be simulated in a laboratory without using a very large voltage?
Very important parameters in HV test:
1. Partial Discharge Test
2. Leakage Test
Here is an article i read regarding HV testing.

I hope you could help me on this. I am currently researching for my thesis and i would really apreciate it if you could throw some ideas and/or suggestions. Thanks.![[IMG]](proxy.php?image=http%3A%2F%2Fwww.engineersedge.com%2Fengineering-forum%2Fimages%2Fsmilies%2Fsmile.png&hash=563bbb5717a829905d11a629d41f04c1)
