High-precision, wideband power analyzers

These instruments have the highest accuracy and are designed to handle the most difficult waveforms whether you’re testing the performance of transformers, lighting or switching electronics such as inverters or power supplies. For very low power factor or high-frequency waveforms, Fluke has solutions that can measure on single-phase, three-phase or six-phase systems.

High accuracy measurements

Fluke Norma Power Analyzers are high-precision power analyzers that accurately measure current and voltage. They also calculate active, reactive and apparent power as well as calculate other derived values from these high-precision measurements. Accuracy is not affected by either the waveform shape nor frequency over a wide range.


All voltage and current channels are separated by a unique technology of barriers for high channel isolation and common-mode rejection. This makes Fluke’s Norma Series of high-precision power analyzers suitable for special applications. For example, the switching waveforms present on variable frequency drives or high-efficiency lighting loads. Each channel combines voltage and current measurement but is isolated from other channels making it possible to measure AC and DC voltages simultaneously on both wye and delta power system configurations.
