Difference between the transient and other event waveforms (power quality analyzers)

QWhy are the waveforms recorded by the PQ3198/PW3198 different between transient and other events?


The PQ3198/PW3198 measures normal power quality items and transient overvoltage separately and differently:
* Normal power quality event:  200kS/s, waveform saved for "2 cycles + 200ms + 2 cycies" after thinning to 20kS/s
* Transient overvoltage:  2MS/s, waveform saved for 2ms before and after detection as 2MS/s data through 5kHz LPF to remove the fundamental  frequency component.
