    Smile ISOLATOR HV Testing elimination?

    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 appreciate it if you could throw some ideas and/or suggestions. Thanks.
