    ABSTRACT: The increase of nonlinear devices in power systems leads us to consider their adverse effects on the waveform distortion, and consequently, the effects and propagation of this harmonic distortion over the whole power system. This paper presents the analysis of the adverse impact caused by the harmonic distortion generated by the thyristor-controlled series capacitor (TCSC) and its interaction with the transmission line. The analysis is carried out on the frequency domain, where total harmonic distortion, apparent power, active power, reactive power, distortion power and power losses are presented under different TCSC operation condition. The analysis of a four-node radial power system exhibiting harmonic distortion because of the TCSC operation is presented.

    ABSTRACT: This paper presents some aspects of power analyzers utilization, related with your calibration by metrological laboratory. The full metrological characterization of power analyzers is a difficult technical process because the specifications in related standard are minimal. After a short presentation of parameters and measurement methods recommended by the important standards in the field of power quality, CEI EN 50160 and CEI EN 61000-4030, study of uncertainty propagation related to test calibration, this document describes the instruments configuration and evaluation of measurement errors and uncertainties for one parameter, voltage in sinusoidal and non-sinusoidal regime.
