text: 14 questions linked to/from How is using a transformer for isolation safer than directly connecting to the power grid?
  I am making a circuit for measuring AC mains voltage and current and I want to avoid using a transformer because it introduces distortions. But everyone says that the circuit will be considered unsafe ...
  I was watching a few different videos by BigClive on youtube. He was mentioning the danger of a particular light chain power supply because it was 'referenced to mains'. The voltage across the output ...
  I want to build a circuit that will eventually calculate power, power factor and thd for a light switch or a wall outlet. But I'm having some problems with the voltage measurement circuit. simulate ...
  Why isolating transformer should be used to protect only one item of equipment at a time? I tried to search and I found this answer, but I could not understand it. This is why, ideally, an ...
  I have read a good discussion about the safety of an isolated transformer. However, in my understanding, the secondary side of the isolated transformer is floating, so will it has a high potential ...

  I have a home workbench and do minor refurb work with old turntables and monitors (CRT) etc. That implies potential exposure to high voltages (mains or above) at power supply capacitors, etc. I have ...
