Measurement of disturbances and compatibility levels on the network: overview and prospects

Given the very specific character of measuring equipment, the measurement of disturbances has long remained a problem to be tackled by specialists. The application of data processing techniques in measurement science is promoting easier use, reduction in costs and standardization of equipment. The feasibility of multi-purpose equipment (harmonics, unbalance, psophometer, etc.) is shown by the authors, together with its applications to fields such as the measurement of the harmonic impedance of the power network
