KONTRAC PN225AC is a trackside converter which is used for dynamic reactive power compensation. It is used in substation facilities 110kV/25kV in which devices for fixed reactive power compensation have already been installed. The converter compensates variable amount of reactive power which can fluctuate considerably during a given time period. The range of compensated reactive power of each converter is from 225kVAr capacitive to 225kVAr inductive. If a higher range of compensated reactive power is needed, it can be accomplished by parallel connection of several converters. The input stage of the converter is made of robust components dimensioned for rolling stock converter applications which makes this converter resistant to spikes, sags and surges that are likely to appear in overhead lines. The use of this proven and reliable technical solution enables significant reduce of excessive reactive power and associated costs, thus making it a perfect solution for sustainable development

KONTRAC GP 550 AC converts the power from transformer outputs of AC network into propulsion power for the traction motors. It has sinusoidal input current in phase with voltage and with low harmonic content. During braking, the converter feeds back energy to the network. All control, protective, communication and monitoring functions are implemented in one control electronics inside the converter.
