− Assessment of power transformer condition is very important for utilities, to ensure continuous power transmission and power supply. Therefore, different techniques are used for condition assessment, as off-line diagnostics and on-line monitoring. The off-line diagnostics has some time period between consecutive diagnoses, and during that period the(More)
− This paper describes the principle of harmonic excitation of strain gages in bridge configuration. This system's properties are mathematically determined and measurements are conducted with commutated excitation, AC and harmonic excitation-with and without filtering. The possibility of increasing the accuracy of output bridge voltage measurement by using(More)
