So what is the significance of the 133 volt spike? Does that mean the actual spike was 188 volts (133v X 1.414 = 188v) which only 11% over the peak voltage, which is no big deal? And why would the voltage be higher on the supply side? Does this mean the surge protector wasn't doing its job by allowing this spike through? Or maybe the spike on the supply side was just 133v RMS? Anyone?
133v RMS would be a typical clamping voltage for a surge suppressor.

No way to know how high the line voltage spiked on the service side.
