Techimp - Altanova Group offers a wide range of sensors and systems to monitor the condition of power transfomer forming them to the unique PD Monitoring for transformer.
 
For PD monitoring of transformer is performed by the means of various sensors, such as:
HFCTs for the cable-terminations of distribution transformer
Tap adaptors to be connected to the test taps of the bushings
UHF spiral antennas for modern transfomer equipped already with inspection windows
UHF horn antennas to be attached to the lower end of the bushing
Acoustic probes
Techimp PD separation technology allows different Partial Discharge (PD) phenomena to be classified on the basis of their pulse shape and split in different clusters (TF map®), so that further analysis can be carried out on each dataset, separately. This enhances the likelihood of PD source identification, even for non skilled operators.
On the basis of the TF map®, it is possible to achieve noise and disturbance rejection, as well as separation of PD phenomena. After separation has been carried out, patterns associated with each phenomenon can be extracted and processed separately, so that the identification of the phenomena causing PD can be carried out through artificial intelligence techniques.
