PST

Getra in its Marcianise factory is able to design, manufacture and test PSTs with power up to 2.000MVA, phase angle displacement up to ± 60 ° and voltage class 800kV.

PSTs are needed to control the power flow between large independent transmission grids and to balance the load when the grids are connected to each other at multiple points in order to have the desired power flow distribution in the different branches.

The use of Phase Shifters Transformers is always a special case because the design criteria are conformed to the specifications and requirements of the individual network. Depending on the overall requirements, there are various types of PSTs that Getra can provide:

• Single Core Symmetrical / Asymmetrical Delta or Delta-Hexagonal
• Double Core Symmetrical
• Double Core Transformer/Autotransformer + Quadrature Booster
