Phase change units
Overview
When transmittinging power over long distances with LXA(C) busbar trunking units, a voltage
drop of varying level occurs. The voltage drop is influenced by the arrangement of the
busbars.
The impedance values (see Technical data (Page 125)) and the resulting voltage drop are
calculated as mean values during type testing.
The use of three phase change units has the effect that the level of the voltage drop
corresponds to this mean value in all three phases. For this, a phase change unit must be
positioned after a third of the total length of the busbar run in each case.
Phase change units are available on request.

Application area
Phase change units are used in the following cases:
●
When the symmetric voltage drop during power transmission has to be kept low
●
In the case of power transmission with high capacity over long distances.
