Selecting the Right Power Analyzer

A power analyzer is used to measure the flow of power (w) in an electrical system. This refers to the rate of electrical transferral between a power source and a sink, hence the alternative expression of power as energy per second (J/s). Measuring power flow is a critical yet rudimentary process that can be carried out with consummate ease using a standard power analyzer. More advanced systems acquire electrical signals and carry out integrated calculations for additional, complex analysis. Although these sophisticated instruments are used in many applications and industries, there is no universal solution to 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

Power Analyzers from HBM

Gain the competitive edge in electrification with HBM Power Analyzers. Designed specifically for the testing of electrical machines and inverters, HBM systems offer significant benefits over conventional power analysers when it comes to electrical machine and powertrain testing.

Premium electrical machine testing from HBM comes in the form of the eDrive solution, which covers the entire measurement chain: high-precision sensors, powerful instruments, and intuitive software. Mechanical signals (e.g. torque) and electrical signals (current and voltage) are acquired simultaneously, helping engineers to better understand the electrical drive and its losses faster and more accurately than ever before.

Two critical selling points of the eDrive electrical machine testing solution include:

  • High accuracy Power Analyzer: Measures and calculates electrical signals and power in real-time on up to 51 channels, as well as mechanical power with up to 6 torque / speed signals and a typical Base Power Accuracy of 0.02%. 
  • High performance Data Acquisition System (DAQ): Synchronous and continuous recording of electrical signals, torque, speed, temperature, acceleration, CAN bus and much more. Real time or post process analysis for result verification, mappings or advanced analysis like electrical and NVH correlations.
