Purpose
Coupling transformers are intended for electric coupling and power exchange between the distribution mains of different voltage classes. For example, between the mains of 20 and 6 kV. Coupling between the mains of different voltage classes allows to increase the reliability of power supply and increase the redundancy level. As for good overload capacity of KPM, LLC transformers – it allows to use them even in the mains with a great variety of modes.
