Cable Rating Calculations for Ground-Mounted Photovoltaic Power Plants

Posted on March 13, 2019

With the increasing number and scale of photovoltaic power plants and their cyclic nature of power generation, accurate cable rating calculations become essential in order to optimize their capacity. This blog post discusses the underlying basic theory, the applicable standards, and their implementation in the web-based cable rating software Cableizer.

Embodied energy and carbon

Posted on June 8, 2018

In order to reduce the carbon footprint it is important that we account for the energy that is embodied in the materials that we use. With Cableizer you can calculate the embodied energy and carbon of any cable.

Heat of Combustion

Posted on March 22, 2018

The gross heat of combustion value - also known as energy value or calorific value - is used to quantify the energy content of a cable in case of a fire. Cableizer calculates the value automatically for each cable.

Considerations for cable laying

Posted on February 27, 2018

The service reliability of a cable systems depends not only on the quality of the cable itself, but also to a large extent on the methods used and the care taken in laying the cable. In this blog post we list some things you should consider.

Two phase concentric cables

Posted on January 21, 2018

A concentric cable has a conductor around the core for a return path. DC cables may be of concentric type as is the case in an integrated return conductor cable, where the return conductor is installed around the core conductor. Such cables are not directly covered by IEC 60287 but Cableizer implemented a method from CIGRE.

Cables crossing external heat sources

Posted on January 20, 2018

With the web-based cable calculation software you can calculate the current rating of cables crossing external heat sources. It allows to calculate the current rating or temperatures of multiple cable systems crossing at any angle multiple other cable systems or heat sources. To our knowledge, Cableizer is the only commercially available software that allows to calculate the crossing of multiple systems with multiple other systems.

Two armour layers with separation

Posted on September 2, 2016

Calculating the ampacity of a cable system correctly starts with the precise modeling of the cable. The user shall be able to model a cable as close to reality as possible, visually, electrically and thermally. As a result from our participation at the Cigré 2016 in Paris, we have now introduced a separation layer between the two metallic armour layers.
