Embodiment Construction

[0017] figure 1 A block diagram illustrating a first embodiment of an electrical power meter arrangement, in particular a smart power meter arrangement, is shown. The power meter arrangement comprises a metering unit 11 configured to be coupled to the power line 100 and to determine power consumption (or more precisely electrical energy consumption). The metering unit 11 measures electrical energy transmitted via the power line 100 . This may be electrical energy delivered from a supplier (not shown) such as a utility company to a consumer (or more precisely to an electrical load 51 (shown in dashed lines) connected to the power line 100 and operated by a user) . However, this could also be energy transferred in the opposite direction from the consumer to the supplier, eg when the consumer operates on a current generating device such as a solar panel.

[0018] The metering unit 11 comprises for example a sensing device 12 coupled to the power line 11 and configured to provi...

Abstract

An electric power meter arrangement, includes a metrology unit configured to be coupled to a power line and to determine power consumption and provide measurement data representing the power consumption. A programmable control unit including a memory is configured to store software configured to run on the control unit. A security unit is configured to store at least one key and to validate that software stored in the memory of the programmable control unit is authorized.

Description

technical field [0001] Embodiments of the present invention relate to an electric power meter arrangement (arrangement), such as a smart electric power meter arrangement. Background technique [0002] An electrical power meter is adapted to measure the power consumption of an electrical load connected to a power line. A power meter is coupled to the power line and measures voltage at and current through the power line to determine power consumption. [0003] Traditional electromechanical power meters include non-electronic displays that show the power that has been consumed since the power meter was installed. Employees of utility companies regularly (usually several times a year) evaluate meter readings in order to calculate power consumption since the last evaluation and to bill customers accordingly. [0004] A smart electrical power meter is an electronic device that is coupled to a power line and adapted to measure power consumption and store measurements representati...
