A single-phase energy meter is an electrical device that is used to measure the amount of electric power consumed by households or commercial outlets.
These meters are also known as credit or KWh meters and are designed to deal only with Alternating current (AC power) rather than Direct current (DC). The meters are available in a variety of sizes depending on the needs of consumers and can be mounted either on a wall or on a DIN rail like other RCDs and MCBs found in homes and businesses.
One of the most important factors in determining the performance of an electrical meter is its ability to resist interference from other devices. This interference is caused by electromagnetic interference (EMI). EMI can travel through wires and cables or even just free space, either via radiation or conduction. This type of interference can cause a significant reduction in the performance of a meter and can result in inaccurate readings. This is why it is very important to design a meter that is not susceptible to EMI. It is also vital to use high-quality equipment for testing electric meters to ensure accurate results.
An electric meter test bench is an electronic system that can be used to perform a variety of tests on a single-phase meter. These systems can help you identify errors, such as those related to the meter’s internal wiring. In addition, they can help you find out if there are any problems with the voltage or current of the meter.
In addition to the standard testing functions of an electric meter test bench, some also include additional tests that are specific to your particular meter. These additional tests include the climatic test and immunity test. The climatic test measures the impact of the environment on your electric meter’s performance, while the immunity test ensures that your meter does not act as an EMI receptor.
The PWS 3.3 genX, from MTE Meter Test Equipment AG, is an advanced single-phase meter tester that features an integrated Portable Working Standard with a class 0.05 % accuracy. This versatile instrument also supports the calibration of DC meters and non-conventional CTs / PTs as well as merging units with SV Sampled Values interface (IEC 61000-4-30 Class A). The PWS 3.3 genX can be used as an electric meter tester for measuring voltage, current, harmonics, power quality, as well as analyzing the impact of electromagnetic interference. This new version of the product also provides a convenient solution for on-site testing of DC charging stations for electric vehicles. It can be used in conjunction with the eMOB I-200.1 DC test adapter for comprehensive on-site testing of charging stations for electric cars. It is a high-performance and cost-effective tool that is ideal for use in testing laboratories and on the field. It is easy to operate and can be customized according to the customer’s needs.
