United in Power Quality - FRANEO 800 IT PQlyzer
Testing the Wide Bandwidth Accuracy of Instrument Transformers for Power Quality
Accurate power quality (PQ) measurements are increasingly essential for maintaining grid integrity, particularly with the global shift towards renewable energy generation. Instrument transformers (ITs) play a vital role in the PQ-measurement chain. To ensure the accuracy of PQ measurement data, it is crucial to evaluate the wideband ratio and phase accuracy of ITs across their entire intended frequency range.
The FRANEO 800 main device and the EIC1 accessory, combined with the new FRANEO PQlyzer software, is a partnership that does just that. This new combination is the perfect match for wideband accuracy instrument transformer measurements for power quality applications.
Why are Instrument Transformer Wideband Accuracy Measurements Important?
Because the impact their ratio or phase accuracy has on in the harmonic frequency range can be significant. Distorted data received by power quality measurement devices can lead to:
- Misinterpretation of power quality events
- Ineffective implementation of corrective actions based on faulty data
- Increased risk of equipment damage due to undetected power quality issues
How Does the FRANEO PQlyzer Work?
The FRANEO PQlyzer system utilizes three key components:
- FRANEO 800: This industry-leading Sweep Frequency Response Analyzer (SFRA) device acts as a measurement platform.
- EIC1 Electronic Impedance Converter: This innovative accessory matches the input impedance (burden) of the test setup with the rated burden of the IT under test, ensuring optimal testing conditions for accurate results.
- The FRANEO PQlyzer software provides a guided workflow optimized for wideband ratio and phase error measurements
"The topic of power quality is trending in our industry. For instrument transformers that are used for measurements at harmonic frequencies, it is especially important to verify their wideband accuracy behaviour. With FRANEO 800 PQlyzer for instrument transformers, this can be done quickly and easily."

A Powerful Duo
FRANEO 800
FRANEO 800 was developed for testing the mechanical and electrical integrity of power transformers after transportation or exposure to high fault currents. It uses the sweep frequency response analysis (SFRA) principle and measures the electrical transfer function over a wide range of frequencies. With our FRANEO 800 you can improve your transformer reliability, reduce maintenance costs and prevent expensive failures.
EIC1
The EIC1 is an electronic impedance converter specifically designed to match the burden of your instrument transformer or low-power instrument transformer.
With this portable solution, you’ll be able to perform wideband ratio measurements quickly and accurately across the entire relevant frequency range.
