As a power consumption metering equipment, electricity meter ,belongs to the metering system installation management, which is used for the metering and billing of electricity, and is the basis for the orderly development of power operation and management. As a metering product, electricity meters involve the livelihood of every household, and the accuracy and reliability of power metering are quite high, and the fairness of measurement must be ensured. For this reason, the national agency has formulated relevant standards, set up a testing and verification department, energy meter products need to pass the authoritative department testing and certification before they can be put on the market, each country and region certification standards are also different: China CPA certification, EU MID certification, the United States UL certification, etc.
For the metering system installation management, there are different test requirements at different stages to meet the requirements of product quality assurance. In the R&D type test stage, the basic error test, latent test, starting test, climate environmental impact test, error consistency test, error repeatability test, durability test, voltage and current change test, harmonic interference test, a variety of EMC interference tests, etc. must be carried out. In the mass production and manufacturing process, the power metering test methods of electricity meters are mainly basic error test, latent test and starting test.
What is the specific implementation principle of the metering system installation management? Generally, the comparative method is used to calibrate and verify the measurement error, and the professional energy meter calibration device is equipped with a standard power source, standard meter and error collector. Install the electricity meter on the calibration device, turn on the power source, and compare the data measured by the energy meter with the calibration device through the pulse interface to form error data. The error data is qualified within the range required by the IEC standard and can be put on the market.
The electricity meter calibration device is a metering equipment, which needs to ensure the accuracy and integrity of the meter calibration device and needs to be controlled and managed. The calibration meter device has a special person for maintenance and management, and the production personnel need to be trained, and only after passing the assessment can they hold a certificate to work, and only then can they be qualified to carry out the operation of calibrating and verifying the electricity meter. Every year, the calibration device should hire professionals from the Provincial Administration of Quality and Technical Supervision to carry out calibration testing to ensure that the equipment is in an accurate and intact state.
Energy meters are metering products and have high technical content, and need to meet the standard requirements and certification requirements of various countries. For the R & D and manufacturing of electricity meters, the threshold is relatively high, for a professional electricity meter manufacturer
Need to have perfect software and hardware conditions. Professional personnel reserve, supply chain, laboratory, production equipment, product quality assurance system, etc. YTL metering , as an electricity meter manufacturers were founded in 1995, nearly 30 years of accumulation and precipitation, customers in more than 60 countries and regions around the world, under the guidance of product leading strategy steady and rapid improvement, forward.
