Harmonic Testing

CLT10 - Danbridge a/s

Defective components are not only unreliable, they are also non-linear. Therefore, effective quality control can be carried out by measuring the distortion of a pure sinewave current through the component. The Danbridge CLT System determines the distortion on the 3rd harmonic, and takes this as an indicator of the reliability and quality of the component. By measuring a component's nonliniarity up to the median value of distortion in a batch of components it is possible to quickly determine pass or fail of the component.
