When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
IEC 60228 is the International Electrotechnical Commission's international standard on conductors of insulated cables. Among other things, it defines a...
Laplace transforms and their inverse are a mathematical technique which allows us to solve differential equations, by primarily using algebraic methods...
A recurring theme on our forums is cable sizing. Now many installations are unique and require special consideration. However, a lot of the time things...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
