Frequency Converter Troubleshooting and Maintenance Tips

by | May 3, 2023 | Blog

Frequency converters are excellent tools that allow electrical devices operating at different wattages to go through a single stable electrical system. Maintaining a single-phase system is great for industries that use technology from other countries or handle more delicate machinery.

If you start to notice your voltage fluctuating more than it should, your converter may be having some trouble. Here are some helpful frequency converter troubleshooting and maintenance tips that will hopefully solve the problem without requiring costly repairs.

1. Thorough Inspection

The first thing you should do is give your converter a thorough inspection and cleaning. You may want to check for exposure to excess humidity or see if your converter is overheating. If there’s a large amount of dust, dirt, or other debris affecting the mechanism, you may want to clear that out. Rotary frequency converters typically have far more moving parts and are more likely to benefit from regular inspections and cleaning. Removing dust and other blockages can reduce overheating and may solve some typical irregularities.

2. Check the Wiring

Loose wiring is a common cause of converter failure. A helpful frequency converter troubleshooting and maintenance tip is carefully examining the connecting wires for frayed or loose cables. Loose connections may cause failing input rectifiers and contribute to overcurrent trips.

3. Test the Input and Output Voltage

When using a frequency converter, you want to balance your voltages within 5 percent. Many converters work to take three-phase power and turn it into a single phase. The cause of your trouble may be that one of these phases isn’t working, in which case your converter will still operate, but not efficiently. Check where the power is going throughout the process and see if you can narrow down whether the issues are in the voltage input or output phase.
