Affecting the operation of electric power networks also affect the measurement of electric energy meter

With the development of modern industry, power grid in a substantial increase in nonlinear loads, in many parts of the supply voltage waveform distortion (ie grid harmonic content increased dramatically), which seriously affect the operation of the power grid also affects the measurement of electric energy meter , giving a great deal of economic power transformers . As we all know, the majority of today's electricity meter or metering induction meter, it is driven components including voltage element and a current element, its role is to alternating voltage and current into  Voltage stabilizer  magnetic flux passing through the turntable, with the interaction of the induced current in the turntable, generating a driving torque, the power meter measured wheel rotation.
