We develop and publish web-based engineering calculation tools. Our tools are carefully designed to have a simple yet comprehensive user interface, to be interactive and more importantly educational. Care is given to document the key aspects of the calculations and reference them to publicly available sources. As a result, the road is paved for those who wish to gain more understanding on the larger context that the tools (like all tools) necessarily simplify.
Cable temperature estimation
This calculation estimates the temperature of cables and buses suspended in free-standing, atmospheric Air under various ambient and current-carrying conditions and constructional features. The estimation is derived from first principles: Resistive Heat losses in the conductor are dissipated solely through natural convection and radiation.
