| Popis: | To date, electrical power in a form of higher-order current harmonics and voltage are reported to be worsening substantially in power lines of industrial and non-commercial consumers. This fact relates to the change of power consumer types to use different household and industrial power receivers. Higher-order harmonic current components cause extra losses in transformers. As a consequence, electrical power delivery is less efficient and losses increase. Therefore, it is necessary to measure harmonic components of current and voltage in distribution networks. The paper presents a measuring tool of loss counter developed on the base of constant coefficients method. Performance and relative accuracy were studied experimentally using a variable-speed drive with the results reported in the paper. The developed measuring tool meets the standards of admitted relative accuracy and is applicable to implement conditionally constant coefficients method in order to calculate excessive losses to be caused by non-sinusoidal loads in transformers of distribution networks. |
