<p>The device (5) has electrical terminals (6, 7) connected to a phase conductor (2) of an electric distribution network (1) and ground, respectively. The device is designed as a two-pole or multi-pole switching network, where impedance and/or admittance of the two-pole or multi-pole switching network is modified continuously or in steps relative to both the terminals by a controller. A primary winding of a transformer or voltage converter is connected with the terminals. An independent claim is also included for a method for injecting an auxiliary signal into a null system of an electric distribution network.</p> |
