DEVICE FOR TRANSVERSE CAPACITIVE COMPENSATION Russian patent published in 2009 - IPC H02J3/18 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, particularly, to device for transverse capacitive compensation in 25kV AC traction circuits. Proposed device comprises switch, capacitor bank, reactor, two resistors and two contactors. Note here that 1^st resistor is shunted by 1^st contactor, while rector shunts the circuit made up of 2^nd resistor and 2^nd contactor connected in series. Switching ON-circuit comprises closing 2^nd contactor block-contact. Note that 2^nd contactor OFF-circuit comprises 1^st contactor closing block-contact. Mind that 2^nd contactor ON-circuit comprises the device ON-button.

EFFECT: reduced voltage and current surges on switching compensation device, higher reliability.
