چکیده:

Non – Linear loads and some non – linear charactristic facility’s electric networks are the main factor to produce distortion in voltage and current sinusoidal waveforms due to induced harmonic in power lines.This is one of the most important problems in electrical industry. Measuring , careful harmonic analysis and operational control are neccessary in different kind of networks (Generation , Transmission and Distribution ) because of , increasing non – linear loads day by day. Poor power quality can result in equipment rnalftinctions and failures or reduced efficiency.
This paper presents , harmonics generated within industrial centers and consumers are identified in Mazandaran electric networks. Then harmonic sources , THD (Total Harmonic Distortion) and configuration registers have been accessible via communication systems and integrated within monitoring networks. Finally, these on – line measurements from some area of Mazandaran electric networks have been studied and compared with standard values to develop corrective strategies.
