NRG-96

Panel Mount Three Phase Kilowatt Hour / kW Demand Power Quality Analyzer

The NRG Series power quality analyzers are highly accurate metering devices which measure the main electrical parameters in three or four wire, single-phase and / or three-phase systems up to 208V.

Measurements are in true effective value (TRMS), using three voltage inputs and neutral (if available) with two or three external current transformers having a …/5A secondary.

These analyzers record active, inductive reactive, capacitive reactive and apparent power per phase and system total. The NRG can also measure harmonics and neutral current, depending on model number. The entire NRG series has a built in power demand meter which calculates integrated demand in a preset period (1 – 60 minutes) using the sliding window method.

These meters can either be stand alone or “ganged” into a single enclosure for multiple metering applications.

In addition to displaying all measured or calculated electrical parameters the NRG analyzers store all parameters into RAM before disruption of power.

Connected to these meters are National Meter’s labeled +/- 0.5% - 1% accurate solid core, split core or bar type current transformers. Please consult NMI application engineer.
