The energy meter for home is an instrument that measures the electricity consumption of a household, serving as the basis for metering and billing of household electricity usage. In China, energy meter for homes are generally installed in locations such as hallways, power shafts, and the entrance walls of each household. Dedicated meter boxes are also provided during installation. After installation, the terminal box cover for the power supply wiring is sealed to prevent unauthorized changes to the wiring sequence.
energy meter for homes are generally available in single-phase and three-phase versions. The use of single-phase prepaid energy meters is increasing in the rental market. Typically, households use single-phase energy meter for homes that have specifications such as a current rating of 5 (60) A, an accuracy class of 1, and communication methods like RS485 or HPLC. Three-phase energy meter for homes are primarily used in villas and standalone homes with large areas and three-phase electrical appliances, such as high-power air conditioners. The main specifications include a current range of 5(80)A or 5(100)A, an accuracy class of 2, and the use of RS485 or HPLC communication. Residential users can view their electricity consumption data through the LCD display on their energy meter for home. Alternatively, they can install the power company's mobile app, register it with their energy meter for home information, and then bind it to view their electricity consumption data.
Single-phase prepaid energy meters are primarily used to measure household electricity consumption by the power company that installs them for metering and billing purposes. Owners install single-phase prepaid energy meters at the output end of their energy meter for home for sub-metering purposes. This is primarily done to manage the electricity consumption of single-room rental properties. There are many urban villages along the coastal areas of China, where each resident has a property with extra rooms. Owners will renovate their extra rooms and rent them out. This requires the independent installation of electricity and water meters for metering and billing purposes.
Appropriate energy meter for homes should be installed based on the actual household electricity consumption needs, including installation methods, specifications, functions, and power supply modes. energy meter for homes must ensure accurate measurements, high sensitivity, good stability, and high safety. As a measuring device, energy meter for homes must undergo testing and certification by authoritative certification organizations before they can be sold. These certifications include China's CPA certification, the EU's MID certification, North America's UL certification, Africa's STS certification, as well as certifications from various other countries and regions. Only after passing certification and being tested can energy meter for homes be used confidently.
