A two-channel digital sampling system for estimating harmonic parameters at low frequencies developed at CENAMEP AIP

A two-channel digital sampling system for estimating harmonic parameters at low frequencies, which utilizes two integrating digital sampling voltmeters in a master-slave configuration, was developed at Centro Nacional de Metrología de Panamá (CENAMEP AIP). A bilateral study was then conducted between Instituto Nacional de Metrologia, Qualidade e Tecnologia (Inmetro) and CENAMEP AIP to compare the estimation results and to evaluate the symmetry of the two digitizing channels.
