Partial Discharge Detector.

The XDP allows to check if a designated site to carry out underground workloads under high voltage is safe
or not. The user sweeps the capacitive sensor on the joints of the cables he wants to inspect and if any are
detected, the XDP then informs him of the shape of the partial discharge signals on many cycles along with
the peak value. What's more, the instrument allows, in "analysis" mode, to proceed in a comparative signal
inspection with the help of its own database, which encompasses ten reference signatures in order to
establish a correspondence with the four nearest signatures to the one obtained on the joint.
It is also possible to record the discharge measurement graphically and in audio form along with the date
and the hour of the reading. The user may also listen to his recording on the premises.
The recorded measurements remain stored in memory even when the XDP is shut off.
This allows the transfer of these recordings to a computer upon return from the worksite.
The ten reference signatures can be listened to anytime and can be replaced to enhance the internal
database of the instrument.
