Electronic energy meter advantage

Electronic energy meter mechanical meter, compared with obvious advantages. Eg tamper capability, high accuracy, load characteristics, the error curve is straight, power factor  circuit breakers  performance is strong, its low power consumption, especially in the measurement of parameters of flexibility, the derived multi-function. Since the application of SCM to the power meter into a new life, which are generally  Circuit breaker  to achieve  mcb circuit breaker  watches. But early electronic energy meter also has some obvious deficiencies, such as shorter working life, susceptible to external interference, operational reliability less mechanical energy meter and so on.
