What to consider when selecting

If your company’s products are powered by inverter-driven electric drives, you already know how critical they are to your business success. HBK Power Analyzers enable development engineers to verify design choices and validate prototypes before going into production or certification.

Power analyzers are multifunctional devices used to measure the flow of power in electrical systems. This is a critical but elementary operation that can be easily performed with a standard power analyzer.

However, innovative power analyzers offer more than just power measurements.
Additional calculations and analytical methods performed with advanced power analyzers include:

  • Efficiency mapping;
  • Fast Fourier Transform (FFT) and harmonic analysis;
  • Fundamental power and root mean square (RMS) values;
  • Polar diagrams and symmetrical components;
  • Space vectors and DQ-currents.

But, while these sophisticated instruments are used in many applications and industries, there is no universal solution that fits every power measurement challenge.

So, what is important to consider when selecting a power analyzer to ensure it fits the needs of your application? We've summarized the answer for you in 5 tips.

  • Tip 1: Accuracy
  • Tip 2: Number and type of inputs
  • Tip 3: Dynamic power measurement
  • Tip 4: Raw data storage and analysis
  • Tip 5: Real-time results

HBK Power Analyzers are the revolutionary systems for testing electrical inverters and electrical machines. Mechanical signals (e.g. torque) and electrical signals (current, voltage) are acquired simultaneously, helping you to better understand the electric drive, its performance and its losses in minutes rather than days. This is important for the optimization of the drive as well as the increase in efficiency. 

In contrast to conventional power analyzers, HBK Power Analyzers offer unique data acquisition and analysis capabilities in addition to power measurement. The modular power analyzers are suitable for any test in electrification for 3-phase as well as multi-channel applications like 6-phase machines, hybrid or multi-motor drives.
