Fluke Norma High Precision Power Analyzers

Category: Power Analyzers

The Fluke Norma Series Power Analyzers are a compact, high performance family of Power Analyzers. Each unit provides the latest measurement technology, assisting engineers with the development and testing of motors, inverters, lighting, power supplies, transformers and automotive components.

The Norma Series are based on a patented, high-bandwidth architecture; The instruments deliver high-precision measurements of single or three-phase current and voltage, harmonics analysis, Fast Fourier Transformation (FFT) analysis, as well as calculations of power and other derived values. The Series consists of the Fluke Norma 4000 Three-Phase Power Analyzer and the Fluke Norma 5000 Six-Phase Power Analyzer. These rugged, high-precision analyzers provide unmatched price performance for easy and reliable use in the field, or as a bench unit in laboratories and on test benches.

Fluke Norma 4000 and Fluke Norma 5000 power analyzers accurately measure current and voltage and calculate active, reactive and apparent power and calculate other derived values from these high-precision measurements. Accuracy is not affected by either the waveform shape or frequency over a wide range. Phase shift accuracy is maintained due to the input channel design. Harmonics are calculated up to half of the sampling rate. The DSO function represents measured input parameters as waveforms. Voltage and current can be measured directly via the instrument’s integrated voltage dividers and shunts. It is also possible to connect external voltage dividers as well as shunts or current probes for specific applications. Options such as additional interfaces, analogue inputs and outputs are also available. The analyzer firmware can be updated via the standard RS232 interface.

Fluke Norma Series power analyzers are designed to measure signals in a wide frequency range from DC to MHz. The input stages are dc coupled and designed to handle high rise time signals. A zero and offset calibration against a stable voltage reference runs automatically over short time periods to stabilize the accuracy. All voltage and current channels are separated by a unique technology of barriers for high channel isolation and common mode rejection. This makes Fluke Norma Series power analyzers suitable for special applications, such as the switching waveforms present on variable frequency drives or high efficiency lighting loads.

 
Electric motors and inverter drive systems Through detailed spectrum analysis and dynamic torque calculation capabilities, switching losses caused by the inverter are accurately measured, and a thorough evaluation is made of torque transients and harmonics at higher frequencies.
Inverter drive system Simultaneous measurement of all electrical and mechanical power parameters in the same time window enables users to observe the influence one component has on another, or on the whole system.
Lighting systems A wide bandwidth of up to 10 MHz and a high sampling rate up to 1 MHz provide detailed signal analysis at ballast outputs. A unique shunt technique enables power measurements at very high frequencies. Simultaneous measurement of input and output power provides instant calculation of ballast losses.
Transformers Synchronous six-phase power measurements enable highly accurate efficiency and loss calculations of large power transformers even at very low power factors. Synchronous multiphase resistance measurements of transformer coils are also possible.
Automotive Synchronous electrical input and mechanical output measurements provide complete data on the efficiency and losses of individual components as well as the whole drive system.
 

The exceptionally high processing power enables precise measurements without gapping, ensuring good results even with rapidly changing signals. Fluke Norma Series power analyzers also maintain high performance and reliable accuracy within the industry’s longest recommended recalibration interval of two years. This long interval reduces downtime and saves service costs.

There are four different measuring channels available for each Fluke Norma Series power analyzer. For the highest level of flexibility and simplicity, you can choose from a variety of standard configurations. This enables users to select the power analyzer best suited to their application’s power measurement requirements.

Each power phase module differs in basic accuracy, current measuring range, sampling frequency, and bandwidth. The input modules can handle up to 10 A or 20 A directly or measure current via wideband precision shunts. The available range of shunts enables measurements up to 1500 A and can be used in conjunction with all of the available input modules.
