Abstract (en)
[origin: WO2014131788A1] The invention relates to an apparatus for heating a pipeline system, comprising at least two pipelines (1) along each of which an electrical resistance heating element extends, characterized in that a potential close to earth potential is established on each electrical resistance heating element at at least one end (3, 5), and the electrical resistance heating element is connected to a pole of a DC power source or to a respective phase (7) of an n-phase AC power source (9) in a position which is remote from said end (3, 5), wherein, when an n-phase AC power source (9) is used, n is an integer equal to or greater than 2.
