    Surge Arrester Testing

    Hi All,

    Can anyone tell me recommended or minimum requirement of Surge Arrester Site Acceptance Test that we can perform at site?

    It would be helpful for me to perform at site.

    NETA ATS Section 7.19.2 will give you the best guidance on this. I can summarize to give you an idea but be sure to refer to the latest standard.

    Visual/Mechanical: Verify nameplate matches project specifications, inspect the installation and appropriate clearances, verify individual ground leads on each device, check stroke counter if present.

    Electrical: Measure resistance through bolted electrical connections and grounding connections using low-resistance ohmmeter and perform insulation resistance test. Watt-loss testing is optional per NETA but I would recommended if available. Test voltages for electrical tests will depend on the voltage class of the arrester.
