    Surge arrestor test for 60 cycle spark over and hold

    I see written on test specifications for a project to "Test for 60 Cycle spark over and hold"
    is anyone familiar with this test? is there documentation on it?

    (also listed in the same spec section is insulation resistance and watts-loss)

    Sounds like maybe a hi-pot test? What is the voltage class? Sometimes we use a hipot to bring up voltage on arresters and look for the point where current starts to spike.

    I'd like to know

    Hipot seems like a good idea. If you figure it out please share.

    This is what I found after a Google search:

    Power Frequency Sparkover Test: This is routine test. This test is conducted using a series resistance to limit the current in case a sparkover occurs. The arrester has to withstand at least 1.5 times the rated value of the voltage for five successive applications. The test is generally done under dry and wet conditions also.

    I wonder if that is more of a factory test? The arrestors I've tested we have just single shot them with the Doble in GST mode. Leakage to ground and go to the next one.
