Electric vehicle charging installations
Electro-Wind specialise in Isolation Transformers for Electric vehicle charging installations and mobile or transportable units.
The application of an isolation transformer to provide an isolated supply for electric vehicle charging equipment will address issues that can arise due to open circuit faults in the PEN conductor of the supply.
The issues with PME
In the event of the distributors PEN conductor becoming broken (open circuit) diverted neutral currents and dangerous touch voltages up to 230V or 400V in three phase systems can appear on any metal work connected to the main earth terminal of the installation. The risk is increased for the person working outdoors as they are
more likely to be in contact with earth.
