The device (10) has a communication unit (22) for wireless presentation of a determined current value on a consumer energy evaluation device. Electrical energy storage (26) e.g. battery, supplies electrical power to an evaluating device (20) and the communication unit, where the device is electrically isolated from a power supply network (12). A magnetic field probe (16) is arranged in an intermediate rack (28) that is inserted in a plug connection (30) among consumer plugs (32) and a connection box (34) and/or connection coupler of the power supply network. The electrical energy storage is selected from battery, accumulator or capacitor. |
