The Research of Transmission Line Power Losses Increasing Caused by Harmonics

The area within the safe supply 66kV substation south chapter of the party , with a line of 10kV line loss Wulong missing instance , describes this line loss increase was mainly caused by two reasons : first, harmonic wave current in the transformer windings ( or line conductors ) flows generated power loss; second winding ( or line wires ) makes the skin effect resistance below the fundamental harmonic resistance, causing the windings ( or line conductors ) of additional losses increase large. By the principle of induction and measurement of electronic energy meter , demonstration will not produce harmonics electronic energy meter error affected and have some impact on the accuracy of the induction meter , but not serious, can demonstrate the harmonic increase in line losses .
