Transformers with longitudinal and quadrature voltage regulation
Special transformers for interconnecting medium-voltage networks with regulation of voltage magnitude and phase. Regulation is performed along the longitudinal and quadrature axes.
- Purpose
- interconnection of MV networks fed from different HV networks
- Regulation
- along the longitudinal and quadrature axes
Price, availability and lead time on request. We help with analogue selection, customs clearance and delivery.
Description
The transformer connects MV networks fed from different HV networks. Longitudinal regulation changes the voltage magnitude, quadrature regulation changes its phase. This matches the voltages and controls the flow between the networks. The design is special for the networks being interconnected.

Questions and answers
What networks are these transformers used for?
For interconnecting medium-voltage networks that are fed from different HV networks.
What does the transformer regulate?
The voltage magnitude by longitudinal regulation and the phase by quadrature regulation.
How does quadrature regulation differ from longitudinal regulation?
Longitudinal regulation changes the voltage magnitude, while quadrature regulation shifts its phase.
