Electricity meters - the inconspicuous heroes of energy consumption
Electricity meters are ubiquitous in our everyday lives, yet often inconspicuous. They hang in our houses and apartments and meticulously record our electricity consumption. But what is actually behind these small devices and how do they work?
An electricity meter, or electricity meter, is a measuring device that records a consumer's electricity consumption and measures it in kilowatt-hours (kWh). It is usually installed near the power connection and consists of various components whose cooperation is crucial for correct measurement.
The core of an electricity meter is the register. Here, the kilowatt hours consumed are recorded and shown on a dial or display. In the past, mechanical counters were used, in which a rotating disk counted the power consumption. Nowadays, digital counters with LCD displays are widely used, which allow precise display.
In order for the electricity meter to correctly record consumption, it must be connected to the electrical circuit. This is where the instrument transformer comes into play, capturing the current flow and converting it into a signal that the meter can understand. There are different types of transducers that are used depending on the application. For example, there are converter types for single-phase or three-phase circuits.
Another important component of an electricity meter is the voltage transformer. This measures the voltage in the circuit and also provides the meter with a corresponding signal. Only when both the current and voltage transformers are functioning properly can the current consumption be recorded correctly.
Modern electricity meters often offer additional functions such as the ability to read current consumption or analyze consumption over a period of time. Some models are even capable of forecasting consumption based on consumption profiles, helping users optimize their power usage.
Electricity meters are not only important for the end consumer, but also for energy suppliers and network operators. They enable accurate billing of electricity consumption and serve as a basis for planning and optimizing power grids. Using data from electricity meters, utilities can better forecast electricity demand and prevent shortages.
In times of increasing environmental awareness and the energy transition, intelligent electricity meters, also known as smart meters, are becoming increasingly important. They enable active control of electricity consumption, for example through time-based tariffs or the integration of renewable energies. Smart meters thus help to make electricity consumption more efficient and sustainable.
Although electricity meters often perform their service unnoticed, they are an indispensable component in our everyday lives. They enable accurate recording and billing of electricity consumption, thus contributing to the efficient use of energy.

How does an electricity meter work and how is electricity consumption measured?
An electricity meter is a device that measures the electricity consumed in a building. It consists of various components that work together to measure electricity consumption.
The main component of the electricity meter is the measuring mechanism, which consists of an electromechanical or electronic system. In an electromechanical electricity meter, the current flow is measured by a rotating disk that is driven by a magnet. The more current flows, the faster the disk rotates. In an electronic electricity meter, the current flow is measured using semiconductors and sensors.
The electricity meter is usually housed in a casing that is sealed to prevent tampering. It is equipped with a display that shows the current power consumption. The electricity meter also has interfaces via which it can communicate with other devices, such as the smart meter gateway.
Electricity consumption is usually measured in kilowatt hours (kWh). One kilowatt hour corresponds to the energy consumed when an appliance with an output of one kilowatt is operated for one hour. The electricity meter continuously measures the current flow and multiplies it by time to calculate the energy consumption.
Electricity consumption is usually measured by the grid operator, who regularly reads the electricity meter. Alternatively, the electricity consumption can also be read by the consumer themselves, for example by reading the display or by using a smart meter gateway that displays the electricity consumption digitally.
The electricity meter is therefore an important part of the electricity grid, as it measures electricity consumption and forms the basis for billing electricity consumption.
