The reactance of series capacitor equipment connected to an electrical transmission power line can be changed during operation with the aid of a transformer on-load tapchanger which switches in or out a variable number of capacitor modules. The tap-changer comprises a tap selector, the contacts of which in currentless state can be moved between the capacitor steps, and a diverter switch with a plurality of sequentially operating contact members and with resistors arranged to prevent direct shortcircuiting of the capacitor steps. The tap-changer can be at line potential and operated remotely by contact-moving means at ground potential. |
