Characteristics
FALCONTM provides an economical solution for continuous monitoring of partial discharge in Medium Voltage equipment that allows to determine the deterioration if the insulation and thus, the eventual worsening of the health condition of the electrical asset before fatal breakdown. FALCON proposes a novel approach to the continuous monitoring of the PD phenomena occurring on an integrated network of Medium Voltage equipment.
Such approach is implemented by addressing the solutions to the requirements of the Medium Voltage grids in terms of non-invasive, low cost and fully automatic PD data acquisitions and elaboration, with the relevant assessment of the conditions of the Medium Voltage equipment.
With onboard computing power and data storage combined with a web-browser interface, the unit can be reached from anywhere in the network allowing to analyze PD data and historic trends with very low data traffic. Easy installation and auto-setting reduces significantly installation times. FALCON provides automatic acquisition and elaboration of PD data, as well as automatic noise rejection and the recognition of the increasing PD trend.
FALCONTM incorporates patented T/F-map technology. The hardware is provided with ultra-wide bandwidth acquisition system, which collects both PD pulse peak and phase, as well as PD pulse waveforms. The pulse waveform allows the information coming from the pulse shape to be employed. Per each acquired pulse the acquisition unit automatically calculates its time and frequency content, building the so called “T-F map”.

- Stand-alone capability
Characteristics
Techimp patented technology allows different PD phenomena to be classified on the basis of their pulse shape, so that further analysis can be carried out on each dataset, separately. This enhances the likelihood of PD source identification, even in the absence of a skilled operator.
Techimp acquisition technology also provides efficient noise rejection. As a matter of fact, noise signals have been observed to be very different from PD signals. Therefore, Techimp classification system can be successful in separating the contributions of PD from those generated by disturbances. Specifically, each PD pulse waveform is acquired and the so-called equivalent time-length and bandwidth are evaluated and plotted on the TF map.
Different types of discharges (e.g. PD due to distributed microvoids, slot discharges and noise in a rotating machine) shall group into different clusters in the TF map being characterized by different pulse shapes.
