Abstract
In a power supply arrangement for supplying electrical power to the pipeline, the power supply arrangement for direct electrical heating of a pipeline system has basically a three phase transformer, a symmetrization unit, and a compensation unit. The three phase transformer is adapted to support a single phase load connected between a first and a second phase of the transformer. The transformer has at least one first tap changer at a high voltage side of the transformer. The symmetrization unit has a first capacitor connected between the first phase and a third phase of the transformer and an inductor connected between the second phase and the third phase of the transformer. The compensation unit has a second capacitor connected between the first phase and the second phase of the transformer. The first tap changer, the first capacitor, the second capacitor and the inductor are adapted to be varied on-load.
