DISAGGREGATION APPARATUS

摘要

The invention relates to a disaggregation apparatus for determining electrical statuses of electrical consumers (2, 3, 4) in an electrical network (4). An overall electrical parameter like the overall current of the electrical network (13) is measured, filtered and sampled. Electrical signatures of the electrical consumers are provided, wherein the electrical signatures are assigned to the statuses of the electrical consumers, filtered and sampled. The filter for filtering the overall electrical parameter and the electrical signatures is adapted for at least one of reducing correlations between the electrical signatures and enhancing the dynamic range for the sampling. The statuses of the electrical consumers are determined depending on the overall electrical parameter and the electrical signatures. The filtering leads to a determination of the statuses of the electrical consumers having a high reliability and a high accuracy.
