how did you protect your lab setup?

Jan Cumps
Jan Cumps over 1 year ago

Participants, now that the experiment is reaching its end: What safety measures did you take when dealing with mains voltages?

I'm starting a road test for a mains powered Flyback design. I'm looking for advice from the players that used their "real mains" to power the experiments.

Things I have at the moment

  • formal education to deal with mains powers
  • a handheld oscilloscope that's isolated and has safe connections
  • a high-voltage differential probe
  • a bench meter that can measure 10 A AC current, and is CAT III 

Did you take other/additional safety measures?

    I would say, the best thing is avoiding mains entirely for the smaller power rating stuff. I use a floating DC Lab supply to run a pure sine wave inverter (300W) as my synthetic mains supply for testing…

    Cover the back of the PCB with insulating tape first. Don't count on friction to hold the PCB in place. Use a power bar and place the OFF/ON switch very near you. I like scottiebabe's tape job. Remember…

    Good questions Jan. When I worked on a mains powered transformer with associated parts: covered every potential touch point with kapton tape just in case. spaced everything out so that there was…

    Last preparation step: I ordered a SMPS textbook a good week ago. It should arrive today.

    As probably you too, I find reading stuff from subject-related books and not just Internet resources alone, benefits me greatly. Doing a course is another level. That looks like a good book!
