Abstract
A compensation device connected in series with power transmission lines having at least one circuit breaker and including at least one compensator unit with a transformerless reactive series compensator having a DC capacitor and a single-phase inverter. A pre-charger pre-charges the DC capacitor of at least one compensator unit. The pre-charger may decouple the DC capacitor from the power transmission lines during pre-charging. The pre-charger may include an AC switch and an AC switch controller opening the AC switch for a time interval (alfa) after a zero-crossing of the line current.
