The Linux Kernel Local Privilege Escalation Vulnerability ("Copy Fail") was fixed on our server.

Induced current on earth continuous conductor (ICE)
Induced current on earth continuous conductor (ICE)

Posted on 2026-04-06
We have introduced a new plot displaying calculated induced currents in earth continuous conductors. These currents are generally undesirable, making the abbreviation ICE an apt choice. Unlike...

Cables in ducts with radiation and convection
Cables in ducts with radiation and convection

Posted on 2026-03-12
To calculate the thermal resistance of the medium in the duct the standard IEC 60287-2-1 uses a method which combines the non-linear heat fluxes into a simplified and linearized formula with...

How the formula for $T'_4$ in IEC was developed
How the formula for $T'_4$ in IEC was developed

Posted on 2026-02-25
In this article we show how the formula for $T'_4$ in IEC 60287-2-1 was derived from the early developments in the 1940's and 1950's to its current form.

Induced voltage on single system (IND)
Induced voltage on single system (IND)

Posted on 2026-02-23
We introduced a new postprocessing plot called "IND" for calculation of induced voltages in the metallic sheaths of a single system as a result of the currents flowing in the conductors. The...

Induced voltage on out‑of‑service cables (WRK)
Induced voltage on out‑of‑service cables (WRK)

Posted on 2026-02-14
We introduced a new postprocessing plot called "WRK" for calculation of induced voltages on a deactivated system as a result of the currents flowing in all other parallel power cables. The method...

Engineers need to know what standard drum dimensions are typically used in order to plan long cable systems where transportation becomes a very important topic.

Sag - downward vertical deflection
Sag - downward vertical deflection

Posted on 2026-01-14
When a cable heats up, it gets slightly longer. If the endpoints stay fixed, that extra length mostly turns into more droop (sag) and lower tension. Engineers estimate the added sag by using a...

Site reference conditions
Site reference conditions

Posted on 2026-01-06
The standard IEC 60287-3-1 contains reference ambient temperatures and thermal resistivities of soil in various countries. We provide you here with an overview of these values per country.
