Considerations on the performance of multi-point synchronized harmonic measurement system

This paper presents a method for assessing the performance of a flexible multi-point measurement system. This system features utilization of the high-precision timing source allowing to record voltages and currents synchronously at different points of the grid. The quality of time synchronization is crucial if high frequency harmonic components are to be evaluated and allocation of emission limits performed. Experimental tests for characterizing the measurement system accuracy for power system harmonics are briefly discussed
