Electricity meters
Make sure your electricity meters measure accurately - and your decisions are based on reliable readings
Electricity meters are found throughout the power system: in homes, buildings, businesses, substations and industrial facilities. They measure electricity consumption, monitor loads and help ensure that the power system works as intended. But for the readings to be useful, the meters must be accurate.
Even small measurement errors can, over time, lead to incorrect billing, make it harder to monitor energy use or make faults in the grid harder to diagnose. If you work in power distribution, meter installation, service or quality control, you need a straightforward and reliable way to test meters.
Reliable readings depend on verified measuring equipment
Electricity meters are a fundamental part of metering systems in power distribution, industry and building energy management. They record active and reactive energy, track load profiles and provide the basis for billing, grid planning and operational monitoring. When you use these readings to make decisions, measurement accuracy and metrological traceability are essential.
Over time, changes in components, load conditions and environmental factors can affect meter performance. Even small measurement errors can have consequences for billing, energy balancing and troubleshooting. Regular testing helps you verify that measuring equipment meets the relevant requirements and provides results you can rely on.
Testing electricity meters can be challenging. There may not be enough load on site to obtain reliable results, or you may need to simulate specific current and voltage values. Testing often also needs to be carried out without unnecessarily interrupting operations.
Our meter testing solutions are designed to meet these needs. Portable test instruments and stationary test systems allow you to check single-phase and three-phase meters, analyse readings on site and document the results. Solutions can be adapted to anything from individual checks to larger, regular testing programmes covering multiple meters.
Solutions for different needs
For laboratories and quality control
Carry out calibration and verification with test systems that can be adapted to your accuracy requirements and workflows.
For service and metering companies
Test meter installations on site, identify measurement errors faster and document your checks with ease.
For industry and property owners
Keep track of energy consumption and measuring equipment, and detect faults before they lead to unnecessary costs or operational disruptions.
For municipalities and public sector organisations
Ensure accurate energy metering with metrological traceability and clear documentation.
Make sure your electricity meters measure accurately
Whether you manage a power grid, run a meter testing laboratory, carry out service work or oversee meter installations in buildings or industrial facilities, we help you ensure that your electricity meters measure accurately.
E-mobility
Keep your charging stations reliable, accurate and ready to use
The growing use of electric vehicles places new demands on charging infrastructure. Whether you operate a charging network, manage charging facilities at a property or oversee public charging points, you need to be able to rely on them every day.
Test charging stations on site
Inaccurate measurements at a charging station can lead to incorrect billing, dissatisfied users and unnecessary costs. Downtime can frustrate drivers, create extra work for your organisation and, in the worst case, result in lost revenue. Safety, regular testing and documentation are also essential.
That is why you need a straightforward way to test charging stations on site. With the right test solution, you can check measurement accuracy, verify the metering data used for billing, detect errors early and document whether the relevant requirements are met.
ZERA’s test solutions help you keep control of your charging infrastructure without making testing unnecessarily complicated. Portable test cases and instruments allow you to test AC and DC charging stations, including fast chargers, on site, whether you manage a single charging point or a larger network.
Solutions for different needs
For charge point operators
Keep your charging network available and support accurate billing. With portable test solutions, you can check charging stations on site, identify measurement errors early and reduce the risk of downtime.
For property owners
Provide safe, reliable charging for tenants, visitors and businesses at your property. Our test solutions help you check that charging stations work as intended and keep maintenance records.
For service companies
Troubleshoot efficiently at your customer’s site. Clear measurement results and portable test equipment help you identify faults faster, carry out checks and document your work.
For municipalities and public sector organisations
Ensure that public charging points are safe, available and meet applicable requirements. Our test solutions provide a practical way to check charging stations and document how they perform over time.
Which test solution is right for your business?
Whether you operate charging stations, manage charging at a property, provide maintenance services or oversee public charging points, we help you ensure that your charging stations operate safely, measure accurately and are ready to use.
