    Abstract: In the field of power transmission networks, particularly high voltage direct current (HVDC) power transmission networks, there is provided an electrical assembly (10). The electrical assembly (10) comprises a converter (12) that includes at least one AC terminal (14A, 14B, 14C) for connection to an AC network (16) and at least one DC terminal (18, 22) which is operatively connected to a DC power transmission medium (20, 24). The electrical assembly (10) also includes a signal injection circuit (32) which is operatively coupled with at least one DC power transmission medium (20, 24). The signal injection circuit (32) includes a signal generator (38) to selectively inject a plurality of different frequency signals into the said at least one transmission medium (20, 24). In addition the signal injection circuit (32) includes a signal analyser (42) to establish a response signature of the said at least one transmission medium (20, 24) to the plurality of different frequency injected signals.
