This invention relates to a power supply point (1) comprising at least one power output (2), and a supply cable (5) which connects the power output to an electric network to electrify the power output (2). In order to detect power supply interference, the power supply point (1) further comprises a current detector (9) which monitors the power supply via the supply cable (5) to the power output (2), and an indicating device (10) which is responsive to the current detector (9) and which indicates a situation where the power supply goes below or exceeds a predetermined limit value. |
