OMICRON speeds up partial discharge localisation

Partial discharges (PD) often occur due to impending insulation faults when electrical and acoustic pulses are sent out simultaneously. OMICRON’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. OMICRON claims that the PDL 650 is an ideal system for localising and analysing partial discharges and tracing back results.

According to the company, the PDL 650 can be combined with the MPD 600 for faster analysis. The MPD 600 measures and analyses electrical partial discharge pulses and is connected to the PDL 650 via a fibre optic cable. UHF measurements can serve as an additional signal input, which the company notes, allows partial discharges to be localised more quickly, even in environments with lots of interference factors.

The PDL software calculates the position of the PD fault and represents this in a 3D model of the transformer. The user can then rotate the model in all directions. According to OMICRON, new transformer models can be created as they are developed, ensuring that the software is prepared for future innovation.

The ‘Record’ function offers new functionalities, allowing complete measurements to be recorded and then played back at a later point in time. All data is saved without changes, therefore the measurement can still be used many years later for comparison or even analysed at a later date.

In many cases, a test report may be desired or even stipulated. OMICRON claims that the PDL software compiles a printable report of the measurements at the touch of a button. For more information, e-mail peter.hosp(at)omicron.at
