A device for investigating a cable system comprising cables and loads. The loads comprise rectifier circuits coupled to storage circuits. The device comprise a charger circuit for producing charging signals for charging the storage circuits such that they have reduced impacts on performances of the investigation signals. The device may further comprise a discharger circuit or a discharging signalling circuit after being charged by the charger circuit. The device further comprises an investigation circuit for producing an investigation signal and a controller circuit for controlling the other circuits and producing the charger signal before the investigation signal. The device may further comprise a reception circuit for receiving responses to the investigation signals and an analysis circuit for analysing the responses in view of the investigation signals and for in response to analysis results defining a problem and/or a location of a problem. |
