<p>Methods and devices to determine values relating to metering a power line signal. A power line signal may be sampled by defining accumulation intervals associated with the power line signal. An accumulation interval may comprise sample periods. Samples are taken during sample periods. Values associated with the samples are determined for each sample period. A sample period may be associated with one or more accumulation intervals. When a sample period belongs to one accumulation interval, the sample period may be allocated to the one accumulation interval. When a sample period is associated with more than one accumulation interval, portions of the sample period may be allocated to the accumulation intervals to which the portions belong. Values determined for a sample period may be allocated to one or more accumulation intervals by allocating the values in relation to the allocation of the sample periods.</p> |
