HIGHLIGHTS
- who: DC active, electrical energy and Christian, Mester from the Federal Institute of Metrology METAS Bern, Switzerland have published the research work: DC active electrical energy meters: Accuracy tests, in the Journal: (JOURNAL)
- what: Comparison method and the energy comparison method.
- how: Calibration and testing must be highly automatised and multiple must be tested at the same time as it is common practice for AC However neither isolated current transformers nor multi secondary voltage transformers exist for This paper proposes an alternative method for simultaneous testing of closed-link that is suitable for . . .
