  • To solve problems that can not be solved using the power triangle,such as determining electric parameters in non-sinusoidal alternating-current circuits with harmonic currents,the power quadrilateral was proposed.A power quadrilateral consists of apparent power S,active power P,reactive power Q,and distortion power N,or is composed of a fundamental harmonic power triangle and a harmonic power triangle.Further,the current quadrilateral and admittance quadrilateral,as well as their similarity to the power quadrilateral in non-sinusoidal alternating-current circuits were derived.Electric parameters such as distortion power,harmonic distortion angle,total harmonic current,distortion admittance and harmonic admittance were calculated using the principle of the quadrilaterals and data collected in-situ.
