Accurate measurement issue: By adopting advanced power measurement technology, it is possible to achieve precise measurement of three-phase four wire power systems, ensuring the accuracy of electricity consumption data. It can not only accurately measure parameters such as active power and reactive power, but also measure electricity quantities such as active power, reactive power, forward active power, reverse active power, forward reactive power, reverse reactive power, and four quadrant reactive power, meeting the power management needs in different scenarios.
Remote management issues: Equipped with intelligent management functions, it can achieve intelligent operations such as remote monitoring, remote meter reading, and electricity data analysis, improving the efficiency and convenience of electricity management. Users can remotely monitor their electricity usage anytime, anywhere, and promptly identify and resolve any abnormal electricity usage issues; Power companies can also monitor users' electricity usage in real-time through remote monitoring, conduct power load dispatch, and optimize power supply.
Electricity fee control issue: It can automatically control the supply of electricity according to the user's preset limit, avoiding the occurrence of excessive electricity consumption or arrears. For public places and rental housing, this function is particularly important as it can effectively avoid wastage and disputes related to electricity bills.
Data storage and transmission issues: It can store electricity consumption data for a long time and upload it to the power management system in real time through a communication interface. Supporting multiple communication methods such as RS485, 4G, Modbus, LoRa, etc., it can adapt to different communication environments and requirements, providing more flexible access methods.
Monitoring of abnormal electricity usage: Equipped with intelligent functions such as automatic diagnosis and self-protection, it can detect the operation of the electricity meter, and actively report theft, operation errors, and common fault alarm information in real time. For example, when the energy meter experiences alarm events such as voltage loss, current loss, reverse phase sequence, overload, reverse power, battery undervoltage, or receives remote alarm commands, the red alarm light of the energy meter will remain on, the buzzer will intermittently sound an alarm, and the meter will output an alarm relay signal.
Electricity analysis and optimization problems: Built in large capacity storage can store a large amount of electricity data, and can also perform data analysis and processing, generate detailed electricity consumption reports and curve charts, help users understand electricity consumption, optimize electricity consumption plans, and achieve efficient energy utilization and sustainable development.
