PDTD68 VLF diagnostics system Datasheet Diagnostics of medium and high voltage cables provides the opportunity for early detection of potential issues, enabling preventive maintenance to be carried out before the cable fails in service. The PDTD68 provides a portable solution for the diagnostics of all kinds of medium voltage cables. It enables simultaneous and sensitive partial discharge (PD) and Tan Delta (TD) diagnostics with sinusoidal operating voltage with constant frequency. The device is specially designed for the use with the HVA very low frequency (VLF) test sets. Complete system: In combination with an HVA test set you get a full-featured and full-value VLF cable test and PDTD diagnostics system for up to 68 kV. 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. Application: PD & TD diagnostics of all kinds of medium voltage cables with length up to 100 km with a portable diagnostics system. Compact and portable: The one single PD device with integrated TD diagnostics and battery or USB-C power. PD localization: Precise & sensitive real time localization of PD faults in cables with 1 % accuracy and resolution of 0.1 pC and 0.1 m. Compliance: Test setup and calibration according to IEC 60270. Additionally, TD testing according to IEEE 400.2.

YOUR BENEFITS PRECISE & SENSITIVE REAL TIME LOCALIZATION PD faults are localized with 1 % accuracy and a resolution of 0.1 pC and 0.1 m. SIMPLE, SAFE & STRAIGHTFORWARD WIRING All that PDTD68 requires is one single communication cable and one DUT cable. SIMULTANEOUS PD & TD MEASUREMENT Parallel PD & TD diagnostics significantly saves time and prevents pre-conditioning of the cable. SINGLE COMPACT & PORTABLE DEVICE The PDTD68 has been designed for maximum portability, resulting in widely applicable device for any type of on-site use. • Sensitive PD measurement due to high coupling capacitance • Compact setup with one single device for PD & TD diagnostics • Easy wiring: one single communication cable and an integrated battery • High noise suppression by the integrated filter • Real-time data assessment of the measured data • Quick and comprehensive reporting ww
