I'm not a 100% sure what you're trying to say, but it sounds like you're probing a live, mains-powered device, & attaching your probe ground to something with lots of volts on it. DON'T DO THAT! - At least isolate the device under test!

Yes use an isolating transformer, do no be tempted to disconnect the ground wire from the scope. That is a trick that people used to do, but it is highly dangerous.

What type/ model of scope are you using? If you don't ground the scope + a fault occurs, the current could go to ground via you. If you are having problems with spikes, and if capturing the waveform is not essential you could connect a choke, or similar, between the probe + oscilloscope.
Just a few thoughts, JD
