Railway workplaces require an extraordinary care for operating with electro technical products. To maintain the required user protection against electrical hazards, it may be necessary to install safety and insulating transformers
Insulation also eliminates that a defective heating element creates a “Track occupied” signal due to a short between the right and left track. Furthermore it eliminates problems with potential differences between the public mains and the rail potential.
