General information
- Short Summary
- An invention by a German university enables a continuously monitoring of power cables for low- and medium-voltage grids, determine the ageing process for electric cables, and generate a service life forecast. The new process can be used to continuously monitor the technical condition of a power cable without interruption of the power supply. The university offers license and/or a technology cooperation agreement.
- Full Description
-
What is the status of the power cables at the distribution grid level? This information is generally not gathered, since conventional methods such as dissipation factor measurement involve a great deal of effort – and then there are the high costs and power disruption for connected customers.
The increased installation of heat pumps, charging stations for e-vehicles, and private solar systems increases requirements for distribution networks and the associated power cables. Heavily fluctuating loads on our low- and medium-voltage grids demand information about whether the power cable in question can provide sufficient power transmission quality or whether it needs to be replaced, which can be expensive.
But an invention by a German university changes all that: It can continuously monitor power cables for low- and medium-voltage grids, determine the ageing process for electric cables, and generate a service life forecast. It also detects the technical condition of the power cables with broadband over power line (BPL) modems that already transfer smart meter data in many power grids.
The system requires at least two BPL modems that can determine and forward the signal-to-noise ratio (SNR) on a broad frequency range (2 to 28 MHz). It also requires a database for storing and analyzing the measured SNR data. The power line signals provide information about power cable quality. Software modules allow the BPL infrastructure to be used for both communication and cable condition assessment.
The university offers a licensing agreement to electrical engineering companies. If interested in further development of the process, the university also offers technological cooperation. - Advantages and Innovations
