liona Online PD Spot Tester

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

Manufactory: BAUR (Austria).

Description

liona allows the testing of cable systems and electrical equipment for partial discharge activities online and without having to switch off, and generates trend analyses. Even a spot test (duration: 5-10 minutes) is capable of reliably assessing the current status of your system. This keeps you constantly informed of when it is necessary to intervene and further maintenance is required, e.g. comprehensive offline diagnostic measurements.

Using the DeCIFer® algorithm by IPEC Ltd, the core of the technology, 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 even possible to precisely locate partial discharges and determine the cable length during operation.

Features

Identifying and locating potential problems before faults occur
Sensitive PD detection in high noise environments due the proven DeCIFer® algorithm
4 simultaneous measurement channels
Automatic PD detection and analysis
Accurate cable PD mapping for defect location
Integrated cable length measurement in combination with the iPD transponder
Easy reporting
Integrated battery or mains operation
Compact, lightweight device that is easy to transport
