Dynamic cable rating software

Ratings for cables installed in air or buried in isolation or in groups can be calculated. The effects of change in conductor resistance with temperature is incorporated. The load profile from table 1 can be plotted displaying the variation in current readings with a range of This can be seen in figure 2. The load factor is defined as the average load divided by the maximum load for a given time period. The following equation is used to attain the load factor.

For the cyclic rating calculations, the Neher-McGrath method is selected using a load factor of 1. Next, using the actual load factor calculated from the data set, an input of 0. As can be seen from figure 3 and figure 4, the permissible peak load current is significantly higher when the load factor is smaller, that is, when the load factor is 1, the permissible current rating is A. When the load factor is 0. This highlights the importance of being able to collect load data as well as finding the average current and load factor of the data set for accurate dynamic cable rating calculations to be made.

We have shown the results are virtually identical under 1. Submarine power cables are not new and have been around for more than a century.

In early times, they were used to supply lighthouses and ships. Dynamic Ratings provides condition based monitoring products and services to the utility industry. We help utilities have better awareness of their high voltage electrical equipment.

From sensors to software, we help utility customers improve transmission and distribution systems reliability, leading to increased maintenance savings and reduced outages. Learn More. With the use of our asset management tools, our power generation and renewable customers realize maximum benefit from online monitoring.

Effective online monitoring provides early warning of condition deterioration by monitoring for partial discharges PD activity. This leads to a safe working environment.
