Fluke Norma Series Power Analyzers
2 models with full specifications from Fluke.
The Fluke Norma Series consists of the Fluke 4000 and Fluke 5000 high-precision, modular power analyzers. These instruments are designed for testing and analyzing single-phase and multi-phase electrical systems, converters, and motors. Both analyzers feature high galvanic isolation across all input channels to ensure user safety and measurement integrity. Engineers and technical buyers can select between these models based on the required number of measurement phases, sample rates, and bandwidth demands of their power electronics applications.

Phase Configuration and Architecture
The primary differentiator between the two models in this series is the phase measurement capacity.
- Fluke 4000: Supports 1 to 3 power phases, making it suitable for single-phase systems, three-phase (3-wire or 4-wire) systems, or multiple independent single-phase configurations.
- Fluke 5000: Features a modular design supporting 1 to 6 power phases. It utilizes a simultaneous parallel acquisition architecture across all phases to ensure synchronized measurements in highly complex multi-phase power electronics.
Both systems feature complete galvanic separation of all inputs to prevent ground loops and preserve signal integrity during high-voltage and high-current monitoring.
Measurement Performance and Software Integration
The Fluke 5000 offers expanded bandwidth options from DC up to 3 MHz or 10 MHz, with selectable sample rates of 102 kHz, 341 kHz, or 1 MHz depending on the specific module configuration. It provides a freely selectable average time ranging from 15 ms to 3600 s, alongside 4 MB of RAM for internal storage of sample or average data.
Both analyzers offer diagnostic capabilities directly on their 144 mm color displays. Supported display modes include numeric readouts, Scope (DSO) mode for waveform viewing, and vector diagram modes for phase alignment. Users can analyze data on a PC using the Fluke NormaView software.
Mechanical and Motor Evaluation
For rotating machinery testing, both the Fluke 4000 and Fluke 5000 can be configured with the PI1 Process Interface. This option allows the analyzers to capture torque and speed measurements from external sensors, directly correlating mechanical performance with electrical input power. Additionally, the PI1 option provides four analog outputs for integrating measurement values into external logging or control hardware.
Frequently asked questions
