First time I’ve learned about the use of the ‘Invert’ switch on the scope, or using an isolation transformer at the device itself to take a measurement. I wonder, though, about the impedance of the isolation transformer affecting the accuracy of the measurement, and again useful only for measuring AC voltages, which is what the scope is most used.

One time, me and a friend were playing electric guitars. He was plugged in to one side of the room, me into the other. We came in to contact in the middle of the room, and pow! We were shocked!

Great video bob. I have a question about transformers. Why do lager transformers operate at lower frequencies and smaller transformers operate at higher frequencies? Why does size play a part. I never fully understood why.

So what if the isolation transformers primary side is grounded? Can't if I touch the hot in the secondary side(which is not grounded), electricity flow through the primary side, since it was grounded?

Great explanations, but what’s the issue with using an isolation transferring on your scope power input even if the case of the transformer is grounded. Agreed it’s not designed you be used that way and there may be noise pickup or something but there’s no chance of electrocution without a fault inside the transformer. The differential probe trick is a great idea though! Thanks

What about welding machine.. is it possible to eliminate interference or voltage spikes on home electric network? Lights are flashing when welding with short circuit mig machine..

Isolation Transformer, seperates one circuit from another, because there is no galvanic connection between the two!
