Waveform - EA Technology UltraTEV Plus2 Operating Manual

EA Technology UltraTEV Plus

5.6.3 Waveform

The 'Waveform' mode is common to both TEV and Cable PD. When in Cable PD mode, values
will be displayed in mA, whilst in TEV mode they will be measured in dBmV as below.
To enter this mode, click the Waveform icon
This mode displays a plot of a TEV or Cable PD activity as a function of time allowing an
instantaneous view of an activity's amplitude with respect to time. This option can be used
to assist in distinguishing between genuine PD activity and noise. A Partial Discharge pulse
will normally manifest as a sharp fast rising edge pulse whilst noise is often slower and
less repeatable.
The Pause and Record option is also available in this mode as described
under the Measure Screen
