Generator Tripping Caused by Severe Current Imbalances Without Voltage Deviations

During our recent PowerXperience, one particular case study generated a great deal of discussion among engineers and industry professionals.

A 490 kW biogas generator repeatedly tripped due to phase current imbalances ranging from 20 A to 200 A. The measured grid voltage remained virtually unchanged. For many participants, this seemed impossible.

The explanation, however, was not what anyone expected.

Following extensive Power Quality measurements and analysis, AEP Hybrid Power identified the root cause of the problem. A practical solution was then developed. Because of the unique nature of this case, we have decided to make the complete technical report available for download.

In this technical report, you will discover:

✔ An overview of the installation and the operational issue.
✔ The measurement approach and practical challenges encountered.
✔ A detailed root cause analysis of the recorded data.
✔ The electrical phenomenon behind the generator trips.
✔ Other situations in which this phenomenon may occur.
✔ A practical solution and recommendations.

Whether you are involved in power generation, grid connections, generator protection, or Power Quality, this real-world case study provides valuable technical insights. It can help identify and prevent similar issues.
