Overhead power lines

Physixfactor simulates the overhead power lines in the Netherlands. Strong magnetic fields must be avoided in areas where permanent residents are planned. The limit in the Netherlands is determined by the government and the RIVM institute issued the regulations for our country.

Schemetic view Transformation station

In the right picture an overview is given of a typical situation around a transformation station. Due to the ever increasing demand of electricity many stations need a dramatic upgrade. In existing stations it is a challinging task to do this, if permanent residence is in the nabourhood. The transformation stations are connected to the over head power grid fir the distribution of electricity.

High Tension masts in the landscape

In the Netherlands many masts decorate the landscape transporting the electricity to other locations.

If residential areas are located too close to the high tension lines then in the Netherlands one should do a verification of the magnetic field strength of the lines. Residential areas are not allowed to be developed when the averaged magnetic field during 1 years is higher than 0.4 microTesla. 

Cross section magnetic fields

When cables are underground the right picture shows the magnetic field lines 2.45 meter underneath the surface. The software is capable of producing many configurations taking into account the 3 phases.  The red contour indicates the 0.4 microTesla intensity line, which in the Netherlands is the value where residential building can be built as long as the exposure is lower than this value.

Sea cables are important for the transportation of electricity. The relatively strong magnetic fields should be investigated prior to operation. Energy losses should be minimal.

With Comsol the magenetic fields are investigated as well as the energy losses with certain configurations.
