Medium Voltage Voltage Transformers

Kappa VTs are designed to minimize  the errors of transformation using the best quality electrical steels for  the core of the transformer and by minimizing the winding drops. Our VTs are robustly designed to provide reliable performance, even under fault conditions. Our designs keep pace with the changing requirements of the electrical power system, and are fully type  tested.
