PRECISE & SENSITIVE REAL TIME LOCALIZATION
PD faults are localized with 1 % accuracy and a resolution of 0.1 pC and 0.1 m.
PDTD68
Get to know the pdtd68
The PDTD68 is an integrated VLF diagnostics system specially designed for the use with HVA VLF test sets. Thanks to its practical design and the single fiber optic interface to the PC it enables a simple and safe measurement setup, which can be built up very quickly.
A large 22 nF coupling capacitor, a built-in filter device and a newly developed data acquisition unit ensure sensitive and accurate PD measurements.
The PDTD68 is also equipped with a battery supply, which allows use in locations without a permanent power source. It can just as easily be powered and charged via USB-C (PD 3.0).

two become one
To make diagnostics on power cables as easy and efficient as possible, we have developed the new PDTD68, which allows simultaneous PD and Tan Delta (TD) diagnostics with one single device.
Complete system
In combination with an HVA test set you get a full-featured and full-value cable test and diagnostics system for up to 68 kV.
Application
PD & TD diagnostics of all kinds of medium voltage cables with length up to 100 km with a quick and easy measurement setup.
PD localization
Precise & sensitive real time localization of PD faults in cables with 1% accuracy and a resolution of 0.1 pC and 0.1 m.
Powerful software
The b2 Suite guides throughout the entire cable testing and diagnostics process. It includes automated PD algorithms and test standard sequences with associated limits.
Compact and portable
The one single PD device with integrated TD diagnostics and battery or USB-C power.
Compliance
Test setup and calibration according to IEC 60270. Additionally, TD testing according to IEEE 400.2.
Characteristics
SIMULTANEOUS PD & TD MEASUREMENT
Parallel PD & TD diagnostics significantly saves time and prevents pre-conditioning of the cable.
SIMPLE, SAFE & STRAIGHTFORWARD WIRING
All that PDTD68 requires is one single communication cable and one DUT cable.
