Arrangement for energy measurement in two separate, multi-phase supply circuits

摘要

The arrangement consists essentially of two mutually independent electronic electricity meters which are arranged in a common, standardised housing and whose current and voltage connections are passed to a common terminal block within the housing. The electronic measurement mechanisms are designed as multi-phase meters. The terminal block (2) has double terminals (1, 4, 7) for the joint connection of the conductors of the same phase of a supply network to in each case two supply leads per phase. The individual terminals of the terminal block (2) are used for the connection of two independent, multi-phase supply circuits. <IMAGE>
