Monitoring an energy parameter in a distribution station

Readout device for querying a monitoring device in a distribution station, comprising:

• an interface for receiving a device identifier of the monitoring device;
• an access unit for determining access information that is based on the device identifier;
• and
• an interrogation unit for transmitting a request to the monitoring device and for receiving an energy parameter from the monitoring device,
• wherein the request comprises the access information, and
• wherein the interface preferably is designed to transmit the energy parameter to a central information collection point.

Method for monitoring an energy parameter in a distribution station with a monitoring device for attachment to a voltage conductor in the distribution station, comprising the steps of:

• measuring an electrical current and/or a voltage of an alternating current flowing through the voltage conductor;
• determining the energy parameter based on the measured electrical current and/or voltage;
• receiving a request from a readout device;
• and
• transmitting the energy parameter to the readout device if the received request comprises access information that is based on a device identifier for uniquely identifying the monitoring device, wherein the device identifier is designed to be read out from immediate spatial proximity.
