Abstract
A meter includes a measuring part (1) and an evaluating part (2). The measuring part (1) contains an open magnetic current transformer (3) of the unloaded transformer type and an integrator (6) connected downstream of the transformer. As a result, no measuring errors caused by saturation occur in the transformer, and the metering of consumption is frequency-independent.
