Today at the Automotive Testing Expo I saw a scope probe by Tektronix that provides electrical isolation that could tolerate very high common mode voltages. Its rated for 2 kV, but the concept in one form or another could possibly be into the millions of volts.
This probe uses a fiber optic cable to provide both power to the probe and return data from the probe. http://info.tek.com/rs/584-WPH-840/images/51W-60485-0_IsoVu_White Paper _TN_3-25-16.pdf
Obviously one could eliminate the fiber cable and use a high intensity light beam to send power to the probe, and use RF or a light beam to return data. So in the extreme hugh voltages could be tolerated.
