However, the PD signals can be distorted
and attenuated when they propagate from their respective
discharge locations to PD detectors. Their rise times and
durations can also be distorted. Therefore, the durations of PD
signals acquired by PD detectors can be significantly different
from the durations of PD signals at their occurrence locations.
Chen and Czaszejko investigated influence of PD detection
circuits with different circuit parameters on the characteristics
of acquired PD signals
