Transformers are static machines that, despite being “dated”, still play a role of primary importance in electromechanical applications. The galvanic separation between the windings that guarantees the disjunction between the primary and secondary circuits in a plant or in an electrical panel and the possibility to vary the input and output voltages, adapting them to […]

The earthing transformer is typically connected between the star center of a three-phase generator and the earth. As illustrated in the drawing below, is the primary that, connected in series to the generator and ground, set up an impedance that may be more or less high depending on the type of the load that will […]

Short circuit limiters are installed in series at the power line and serve to reduce the short circuit currents. The current reduction can also occur for other reasons, such as sarting up electric motors or severe inductive machines. The main advantage of this type of reactor is that you can installing circuit breakers with lower […]
