Performing measurements
34
This histogram shows the measured values from the last 10 seconds in dBµV (averaged
per second).
The bar at the bottom shows the maximum value measured within the last 10
measurements. The average measurement displayed (
Avg
) also refers to the last
10 seconds.
This screen shows the course of the pulse-per-cycle values measured over the last
10 seconds.
The value is updated every second, i.e. the value is averaged over the mains voltage
periods occurring within one second.
The bar at the bottom also specifies the maximum value measured in this case.
The PRPD diagram (phase resolved partial discharge) provides information about the
distribution of the measured PD pulses over a mains voltage cycle (X-axis).
To do so, the levels (Y-axis / dBµV) and relative phasing (X-axis / ms) of the measured
PD pulses are plotted in a diagram. If multiple pulses with exactly identical coordinates
(level and phase relationship) are measured, then the respective dot in the diagram
gradually changes colour from green to red in accordance with the colour scale shown.
