PDTD60-2 Partial Discharge Diagnostics System

The diagnostic system PDTD60-2 (in combination with a VLF generator1) enables comprehensive diagnosis with sinusoidal output voltage with constant frequency, which is a prerequisite for the comparison of PD and TD measurement results of cables with different lengths. Load-dependent and therefore constantly changing measurement frequencies offer no basis for this. The sine wave output voltage is the only described VLF voltage form in IEEE400.2-2013 for partial discharge and tan delta measurements and provides clear procedures and quality control procedures. The comprehensive monitoring and diagnostics software b2 Suite® makes the process easier and leads you through the diagnostics process. The database solution of b2 Suite® allows to process the data quickly and can be retrieved at any time.
