Measuring methods and measuring device for determining a tariff magnitude for energy consumer

摘要

In a measuring process for determining a tariff value for energy consumed, fixed quantity pulses are produced by means of a pulse generator 6 associated with a consumption meter 3. Measurement values which are proportional to the reciprocal of the time intervals between the fixed quantity pulses are summed in a summing means 9. The expectation value P of the power, the quotient of the expectation value P and the mean value P of the power, and the form factor of the load curve, are determined in an evaluation device 11, from the measurement value Z2 of the summing means 9 and the measurement value Z1 of the consumption meter 3. The summing means 9 and the consumption meter 3 are connected to the evaluation device 11 by way of a communication channel 10. A microprocessor may be used for determining the reciprocal.
