Cable diagnostics… the next generation

Network operators can now get faster and significantly more reliable information about the quality and the condition of their cables. This is made possible thanks to the brand-new 50 Hz Slope technology. For the first time, it has become possible to immediately locate faults in underground cables during the actual partial discharge (PD) measurement.

With the 50 Hz Slope technology, for the first time worldwide a withstand test with very low frequency cosine-rectangular (VLF CR) voltage and PD diagnosis with damped alternating voltage (DAC) is combined in one unit. This allows an efficient and integrated solution for precise inventory of the network infrastructure. The important fact here is that the PD measurement data, gained with the VLF CR or with the DAC test voltage, can be compared directly with the 50 / 60 Hz network voltage.

This facilitates reliable decision making.
