Acoustic partial discharge localisation
Partial discharges (PD) often occur due to impending insulation faults when electrical and acoustic pulses are sent out simultaneously. Omicorn's PDL 650 localises the acoustic signals using multiple sensors spread out over the transformer. The PDL software then calculates the fault location based on the time difference between the incoming signals.

The PDL software then calculates the fault location based on the time difference between the incoming signals.
The PDL 650 can be combined with the MPD 600. An MPD 600 reliably measures and analyses electrical partial discharge pulses and is connected to the PDL 650 via a fiber optic cable. UHF measurements can serve as an additional signal input. This allows partial discharges to be localised more quickly, even in environments with lots of interference factors.
The 3D depiction of the transformer is particularly useful. The PDL software calculates the position of the PD fault and then represents this in a 3D model of the transformer. The user can then rotate the model in all directions.
