1. A meter for recording an electrical energy withdrawn from an electrical supply network, the meter comprising:
- a first component for measuring a currently supplied supply voltage; and
a computing element for determining an operation state of the meter for calculating a billing unit based on a currently withdrawn electrical energy,wherein the operation state is modified in accordance with the measured supply voltage independent of electrical consumption, such that the currently supplied supply voltage that is higher or lower than a nominal voltage causes the computing element to determine that the meter is to be operated under a modified operation state based on a value of the currently supplied supply voltage that is respectively higher or lower than the nominal voltage to define the billing unit,wherein under the modified operation mode state, a correction factor used to adjust the billing unit is formed based on the nominal voltage of the supply network relative to the currently supplied supply voltage, andwherein the correction factor increases disproportionately as the measured supply voltage decreases when the measured supply voltage is less than the nominal voltage and the correction factor decreases disproportionately as the measured supply voltage increases when the measured supply voltage is greater than the nominal voltage, andwherein the billing unit is determined based on an amount of energy used and is adjusted by the correction factor.

Abstract
A meter for recording or determining the electrical energy withdrawn from an electrical supply network or supplied to it is provided. The meter including a component for measuring the current supply voltage, and a component for determining the operating mode based on the currently withdrawn or supplied electrical energy, wherein the operating mode can be changed, depending on the measured supply voltage, in such a way that a relatively high supply voltage causes a slower metering process than a comparatively low supply voltage.

13. An electrical energy meter device,
wherein the electrical energy meter device records an electrical consumption of electrical energy and/or electrical power withdrawn by a consumer from an electrical supply network, or for capturing the supply of electrical energy and/or electrical power which has been rendered by an energy generator to a supply network, and wherein dependent upon a supply voltage at the electrical energy meter device, an operation state of the electrical energy meter device is changed such that when the supply voltage at the electrical energy meter device is higher than a first predetermined voltage amount, the electrical energy meter device determines a billing unit as a basis for a lower billed amount than at a supply voltage lower than the first predetermined voltage amount, and that when the supply voltage at the electrical energy meter device is lower than a second predetermined voltage amount, the electrical energy meter device determines a billing unit as a basis for a higher billed amount than at a supply voltage higher than the second predetermined voltage amount.

22. An electrical energy meter device connectable to an energy supply network that supplies electric energy from at least one power source, comprising:
-
an input terminal that receives the electric energy or electric power supplied from the energy supply network; a computing element that adjusts a billing unit based on a supply voltage amount available at the input terminal and calculates a billing amount based on the adjusted billing unit, wherein, when the supply voltage amount available at the input terminal is higher than a predetermined supply voltage amount, the computing element disproportionately decreases the billing unit based on the supply voltage amount being more than the predetermined supply voltage amount, and when the supply voltage amount available at the input terminal is lower than the predetermined supply voltage amount, the computing element disproportionately increases the billing unit based on the supply voltage amount being less than the predetermined supply voltage amount. - View Dependent Claims (23)
