Design of Three-phase multi-function energy meter based on measurement chip RN8302
According to the development status of the energy meter, we put forward a design of a Three-phase multi-function energy meter based on professional measurement chip RN8302 and High-performance single chip microcomputer MSP430 in this article.It has the characteristics which are low-power consumption, high-precision and electricity anti-theft.It could also real-time measured current, voltage, active power, reactive power, power factor, over-voltage and over-current signal.The design also has the functions of surge prevention, lightning prevention and voltage protection, improving the overall safety and reliability of the system.Use the Low-voltage power line carrier communication, there is no need to build another peripherals,saving the cost of grid investment.The article also gave the overall design scheme and the main hardware principle Schematic.
