Energy meter readings
SMC 133 has an embedded three phase, four-quadrant energy meter with automatic meter reading functions and
multiple programmable tariffs (Time-of-Use, TOU). The instrument registers active energy (EP, EP+, EP-) and
reactive energy (EQL, EQC or EQC+, EQC-, EQL+, EQL-). According to the configuration of meter readings
are shuffled to the respective tariffs. It automatically provides summaries per phase. For star connections and
single phase measurements it can also register energy for each phase separately.
Meter data readings can be downloaded and analyzed in ENVIS or via the standard ModBus protool in any
other system.
