Tariff device in conjunction with a elektrizitaetszaehler and a plurality of counters

摘要

The tariff device is connected with its housing (2) to the electricity meter (1). It is used for detecting the power consumption by means of a number of counting devices (3, 4) which can be optionally switched in. The various counting devices (3, 4) are alternately switched in as a function of the power currently taken by the load. The power limits can be set by a selection switch (7). In addition, the number of transgressions of a set power limit are detected in a pulse counting mechanism (6) and a counting mechanism (5) indicates the total consumption. IMAGE
