BAUR – liona

Reliable, cost saving, easy to use

↗ Online PD testing of cable routes during normal cable network operation
↗ Automatic evaluation of the PD: no expert knowledge necessary
↗ Unique new technology based on artificial reflections for online PD mapping
↗ Detection of faraway PD by means of patented frequency response modification with VDS PD coupler

liona is a portable online PD spot tester for measuring and locating partial discharges in cables and switchgear during normal mains operation.

liona lets you test cable systems and switchgear online without switching off partial discharge activities, and then generate trend analyses. Even a PD spot test (duration: 2 – 3 minutes) is capable of reliably assessing the current status of your system. This keeps you constantly informed of when in it necessary to intervene and further maintenance is required, e.g. comprehensive offline diagnostic measurements.

Using the DeCIFer® algorithm, the core of the software, the unit is able to clearly differentiate between noise signals and partial discharges. liona therefore provides meaningful results even in environments with high noise levels.

With the iPD transponder – available as an optional extra – it is possible to precisely
locate partial discharges and determine the cable length.
